Bronchoscopic lung volume reduction significantly increased survival in patients with severe chronic obstructive pulmonary disease, based on data from more than 1,400 individuals.

Previous studies have shown that patients with severe chronic obstructive pulmonary disease (COPD) can benefit from treatment with bronchoscopic lung volume reduction (BLVR) involving lung volume reduction coils or endobronchial valves (EBVs) in terms of improved pulmonary function, lung volume, exercise capacity, and quality of life.

However, data on the impact of the procedure on patient survival are limited, and most previous studies have been small, wrote Jorine E. Hartman, MD, of the University of Groningen, the Netherlands, and colleagues.

In a study published in Respiratory Medicine, the researchers reviewed data from 1,471 patients with severe COPD who had consultations for BLVR at a single center between June 2006 and July 2019. Of these, 483 (33%) underwent a BLVR treatment.

The follow-up period ranged from 633 days to 5,401 days. During this time, 531 patients died (35%); 165 of these (34%) were in the BLVR group.

Overall, the median survival of BLVR patients was significantly longer, compared with those who did not have the procedure, for a difference of approximately 1.7 years (3,133 days vs. 2,503 days, P < .001). No significant differences in survival were noted in BLVR patients treated with coils or EBVs.

The average age of the study population at baseline was 61 years, and 63% were women. Overall, patients treated with BLVR were more likely to be younger and female, with fewer COPD exacerbations but worse pulmonary function, as well as lower body mass index and more evidence of emphysema than the untreated patients, the researchers noted. Patients treated with BLVR also were more likely than untreated patients to have a history of myocardial infarction, percutaneous coronary intervention, or stroke.

However, BLVR was a significant independent predictor of survival after controlling for multiple variables, including age, sex, and disease severity, the researchers noted.

The current study supports existing literature on the value of BLVR for severe COPD but stands out from previous studies by comparing patients who underwent BLVR with those who did not, the researchers noted in their discussion of the findings.

The study findings were limited by several factors, including the fact that the non-treated patients were not eligible for treatment for various reasons that might have impacted survival, the researchers noted. Another limitation was the lack of data on cause of death and other medical events and treatments during the follow-up period, they said.

However, the results were strengthened by the large sample size and long-term follow-up and suggest that “reducing lung volume in patients with COPD and severe hyperinflation and reduced life expectancy may lead to a survival benefit,” they concluded.

The study received no outside funding. Dr. Hartman had no financial conflicts to disclose.

The heart from a genetically modified pig transplanted to a Maryland patient in January in a pioneering, acclaimed, and widely critiqued surgery appears to have carried an unwanted passenger.

A porcine cytomegalovirus (PCMV) in the heart had gone undetected before the operation and may or may not have been instrumental in David Bennett’s death 2 months later, according to a report published in MIT Technology Review.  

University of Maryland Medical Center

“The issue is now a subject of wide discussion among specialists, who think the infection was a potential contributor to Mr. Bennett’s death and a possible reason why the heart did not last longer,” states the article, written by staff journalist Antonio Regalado.

As described in the story, the xenotransplant saga’s new twist comes from the surgeon who performed the operation, Bartley P. Griffith, MD, University of Maryland, Baltimore, who related the PCMV finding in an April 20 online presentation hosted by the American Society of Transplantation.

Mr. Bennett’s initially promising but later turbulent clinical course, described by his surgeons and widely reported upon his death, included repeated skirmishes with infection and retaliatory adjustments to his immunosuppressant regimen. Those episodes were thought to have contributed to his death, the actual cause of which is undetermined or at least not yet reported.

“We are beginning to learn why he passed on,” Dr. Griffith said in Mr. Regalado’s article, acknowledging further that the porcine virus “maybe was the actor, or could be the actor,” that set off the events leading to Bennett’s death.

Xenotransplant specialists know that PCMV is a potential problem with pig organs and know to test for it before attempting the procedure in animal models, notes the article. It refers to a published series of pig-heart transplants to baboons in Germany. The hearts “lasted only a couple of weeks if the virus was present, while organs free from the infection could survive more than half a year.”

The heart Mr. Bennett received had been extensively screened for bacteria, viruses, and other issues that could have threatened the organ and Mr. Bennett, but the effort apparently fell short. In the MIT Technology Review story, the first author of the German baboon series speculates on how the University of Maryland team might have missed PCMV.

“The U.S. team appears to have tested the pig’s snout for the virus, but often it is lurking deeper in the tissues,” Joachim Denner, PhD, Institute of Virology, Free University of Berlin, said in the article. The virus, he contended, “can be detected and easily removed from pig populations, but unfortunately they didn’t use a good assay and didn’t detect the virus.”

That PCMV escaped detection before the operation “could now factor into some people’s questions over whether the experiment should have taken place at all,” the MIT Technology Review article proposes. “It’s a big red flag,” bioethicist Arthur Caplan, PhD, New York University, said in a quote, adding: “If doctors can’t prevent or control infection, ‘then such experiments are tough to justify.’ ”

The U.S. Food and Drug Administration has approved mavacamten (Camzyos, Bristol Myers Squibb) to improve functional capacity and symptoms in adults with symptomatic New York Heart Association (NYHA) class II-III obstructive hypertrophic cardiomyopathy (oHCM).

Mavacamten is the first FDA-approved allosteric and reversible inhibitor selective for cardiac myosin that targets the underlying pathophysiology of the genetic disorder. It’s available in 2.5-mg, 5-mg, 10-mg, and 15-mg capsules.

“The approval of Camzyos represents a significant milestone for appropriate symptomatic obstructive HCM patients and their families, who have long awaited a new treatment option for this chronic and progressive disease,” Anjali T. Owens, MD, medical director of the Center for Inherited Cardiac Disease and assistant professor of medicine, University of Pennsylvania, Philadelphia, said in a news release.
 

‘Revolutionary’ change

The approval of mavacamten was based on data from the pivotal EXPLORER-HCM and EXPLORER-LTE (long-term extension) trial of adults with symptomatic NYHA class II-III oHCM.

In EXPLORER-HCM, treatment with mavacamten over 30 weeks led to significant improvement in exercise capacity, left ventricular outflow tract (LVOT) obstruction, NYHA functional class, and health status, as reported by this news organization.

The safety and efficacy findings seen at the end of the blinded, randomized, initial 30-week phase of EXPLORER-LTE were maintained in patients who continued treatment for a median of about 62 weeks.

Mavacamten represents “an almost revolutionary change” for the treatment of oHCM, Maya E. Guglin, MD, professor of clinical medicine and an advanced heart failure physician at Indiana University, Indianapolis, said during a press briefing earlier this month at the American College of Cardiology 2022 Scientific Session earlier this month.

“Until now, there was no good medical treatment for symptomatic oHCM. This will change the landscape, and without question it will change guidelines for treating oHCM,” Dr. Guglin said.

The product information for mavacamten includes a boxed warning citing a risk for heart failure.

Echocardiogram assessments of left ventricular ejection fraction (LVEF) are required before and during treatment.

Starting mavacamten in patients with LVEF below 55% is not recommended and the drug should be interrupted if LVEF falls below 50% at any visit or if the patient experiences heart failure symptoms or worsening clinical status.

Concomitant use of mavacamten with certain cytochrome P450 inhibitors or discontinuation of certain cytochrome P450 inducers can increase the risk for heart failure attributable to systolic dysfunction. Therefore, its use is contraindicated in patients using moderate to strong CYP2C19 inhibitors or strong CYP3A4 inhibitors, and moderate to strong CYP2C19 inducers or moderate to strong CYP3A4 inducers.

Because of the risk for heart failure attributable to systolic dysfunction, mavacamten is only available through the Camzyos Risk Evaluation and Mitigation Strategy (REMS) Program.

BOSTON – According to the best available data, solid organ transplant recipients (SOTRs) at highest risk for developing skin cancer are thoracic organ recipients, those aged 50 or older at the time of the transplant, and males.

White patients who meet these criteria should be screening within 2 years after transplant, while Black patients should be screened within 5 years after transplant, Ally-Khan Somani, MD, PhD, said at the annual meeting of the American Academy of Dermatology.

Dr. Somani, director of dermatologic surgery and the division of cutaneous oncology at Indiana University, Indianapolis, based his remarks on consensus screening guidelines assembled from three rounds of Delphi method surveys with 47 dermatologists and 37 transplant physicians, with the goal of establishing skin cancer screening recommendations for SOTRs. Among the dermatologists surveyed, 45% were Mohs surgeons and 55% were general dermatologists.

The panel recommended that the transplant team should perform risk assessment for SOTRs to risk stratify patients for skin cancer screening (high risk vs. low risk). They also proposed that dermatologists perform skin cancer screening by full-body skin examinations, and that SOTRs with a history of skin cancer should continue with routine skin cancer surveillance as recommended by their dermatologists.

Those at low risk for skin cancer include abdominal organ recipients, SOTR age of younger than 50 at time of transplant, and female gender. The guidelines recommend that White, Asian, and Hispanic patients who meet those criteria should be screened within 5 years after transplant, while no consensus was reached for Black patients who meet those criteria.

Based on posttransplant skin cancer incidence rates, risk is increased among males, Whites, thoracic organ recipients, and being age 50 or older, Dr. Somani said. “At our institution, we make sure there’s a good connection between our transplant teams and dermatologists. We recommend rapid referral for suspicious lesions and we educate patients and screen them within 1 year of transplant, or sooner for high-risk patients. Surveillance is increased to every 3 or 4 months for patients with a history of multiple or high-risk cancers or sooner, followed by routine surveillance as recommended by the patient’s dermatologist.”

To risk stratify patients on the development of their first skin cancer post transplantation, researchers developed the Skin and Ultraviolet Neoplasia Transplant Risk Assessment Calculator (SUNTRAC), a prediction tool with a freely available app. Data for the tool were drawn from the Transplant Skin Cancer Network study, a 5-year analysis of 6,340 adult recipients of a first solid organ transplant at 26 transplant centers in the United States. It generates a risk score for SOTRs (low, medium, high, or very high), which informs transplant care providers of a patient’s risk of skin cancer.

Dr. Somani disclosed that he has received grants and funding from Castle Biosciences. He is an adviser to Cook Biotech and a consultant to Sanara MedTech.

It generates a risk score for SOTRs (low, medium, high, or very high), which informs transplant care providers of a patient’s risk of skin cancer.

In a deep dive into obscure Chinese language transplant journals, a pair of researchers from Australia and Israel have added a new layer of horror to what’s already known about forced organ harvesting in China.

Searching for documentation that vital organs are being harvested from nonconsenting executed prisoners, a practice that the China Tribunal confirmed “beyond any reasonable doubt” in 2020, Jacob Lavee, MD, an Israeli heart transplant surgeon, and Matthew Roberston, a PhD student at Australian National University, uncovered something even more shocking: that vital organs are being explanted from patients who are still alive.

“We have shown for the first time that the transplant surgeons are the executioners – that the mode of execution is organ procurement. These are self-admissions of executing the patient,” Dr. Lavee told this news organization. “Up until now, there has been what we call circumstantial evidence of this, but our paper is what you’d call the smoking gun, because it’s in the words of the physicians themselves that they are doing it. In the words of these surgeons, intubation was done only after the beginning of surgery, which means the patients were breathing spontaneously up until the moment the operation started ... meaning they were not brain dead.”

The research, published in the American Journal of Transplantation, involved intricate analysis of thousands of Chinese language transplant articles and identified 71 articles in which transplant surgeons describe starting organ procurement surgery before declaring their patients brain dead.

“What we found were improper, illegitimate, nonexistent, or false declarations of brain death,” Mr. Robertson said in an interview. He explained that this violates what’s known as the dead donor rule, which is fundamental in transplant ethics. “The surgeons wrote that the donor was brain dead, but according to everything we know about medical science, they could not possibly have been brain dead because there was no apnea test performed. Brain death is not just something you say, there’s this whole battery of tests, and the key is the apnea test, [in which] the patient is already intubated and ventilated, they turn the machine off, and they’re looking for carbon dioxide in the blood above a certain level.”

Mr. Robertson and Dr. Lavee have painstakingly documented “incriminating sentences” in each of the 71 articles proving that brain death had not occurred before the organ explantation procedure began. “There were two criteria by which we claimed a problematic brain death declaration,” said Mr. Robertson, who translated the Chinese. “One was where the patient was not ventilated and was only intubated after they were declared brain dead; the other was that the intubation took place immediately prior to the surgery beginning.”

“It was mind-boggling,” said Dr. Lavee, from Tel Aviv University. “When I first started reading, my initial reaction is, ‘This can’t be.’ I read it once, and again, and I insisted that Matt get another independent translation of the Chinese just to be sure. I told him, ‘There’s no way a physician, a surgeon could write this – it doesn’t make sense.’ But the more of these papers we read, we saw it was a pattern – and they didn’t come out of a single medical center, they are spread all over China.”

For the analysis, Mr. Robertson wrote code and customized an algorithm to examine 124,770 medical articles from official Chinese databases between 1980 and 2020. The 71 articles revealing cases involving problematic brain death came from 56 hospitals (of which 12 were military) in 33 cities across 15 provinces, they report. In total, 348 surgeons, nurses, anesthesiologists, and other medical workers or researchers were listed as authors of these publications.

Why would these medical personnel write such self-incriminating evidence? The researchers say it’s unclear. “They don’t think anyone’s reading this stuff,” Mr. Robertson suggests. “Sometimes it’s revealed in just five or six characters in a paper of eight pages.” Dr. Lavee wonders if it’s also ignorance. “If this has been a practice for 20 or 30 years in China, I guess nobody at that time was aware they were doing something wrong, although how to declare brain death is something that is known in China. They’ve published a lot about it.”

The article is “evidence that this barbarity continues and is a very valuable contribution that continues to bring attention to an enormous human rights violation,” said Arthur Caplan, PhD, head of the Division of Medical Ethics at New York University’s Grossman School of Medicine. “What they’ve reported has been going on for many, many years, the data are very clear that China’s doing many more transplants than they have cadaver organ donors,” he said, adding that the country’s well-documented and lucrative involvement in transplant tourism “means you have to have a donor ready when the would-be recipient appears; you have to have a matched organ available, and that’s hard to do waiting on a cadaver donor.”

Although the researchers found no incriminating publications after 2015, they speculate that this is likely due to growing awareness among Chinese surgeons that publishing the information would attract international condemnation. “We think these practices are continuing to go on,” said Dr. Lavee. He acknowledged that a voluntary organ donation program is slowly developing in parallel to this. He said, given China’s place as the world’s second largest transplant country behind the U.S., as well as its low rate of voluntary donation, it’s reasonable to conclude that the main source of organs remains prisoners on death row.

Dr. Caplan and the researchers have called for academic institutions and medical journals to resume their previous boycotts of Chinese transplant publications and speakers, but as long as China denies the practices, economic and political leaders will turn a blind eye. “In the past, I don’t think the question of China’s medical professional involvement in the execution of donors has been taken as seriously as it should have,” said Mr. Robertson. “I certainly hope that with the publication of this paper in the leading journal in the field, this will change.”

The study was supported by the Google Cloud Research Credits program, the Australian Government Research Training Program Scholarship, and the Victims of Communism Memorial Foundation. Mr. Robertson, Dr. Lavee, and Dr. Caplan have disclosed no relevant financial relationships.

The rates of infection involving cardiac implanted electronic devices (CIEDs), like pacemakers and cardioverter defibrillators (ICDs), are substantial, but only a minority of patients in the United States receive the guideline-directed recommendation of device removal, according to data from a Medicare population.

The study was conducted on the hypothesis that adherence to guidelines were low, “but we were surprised by how low the extraction rates turned out to be,” Sean D. Pokorney, MD, an electrophysiologist at the Duke Clinical Research Institute, Durham, N.C., reported at the annual scientific sessions of the American College of Cardiology.

The major U.S. and European guidelines are uniform in recommending complete extraction for a CIED infection. The American Heart Association and the Heart Rhythm Society and two out of the three other guidelines cited by Dr. Pokorney not only recommend extraction but specify prompt extraction.

Neither complete extraction nor prompt extraction are typical.

Of the 11,619 CIED infection cases identified in the Medicare database, 18.2% underwent extraction within 30 days of diagnosis. Only 13% were extracted within 6 days.
 

Lack of extraction may cause avoidable mortality

The result is likely to be avoidable mortality. Among those with extraction within 30 days, 80% were still alive 1 year later. Survival at 1 year fell to 67.6% in those without an extraction within this time frame.

This translated to a 22% lower rate of death at 1 year (hazard ratio, 0.78; P = .008) in those who underwent extraction within 30 days.

For those in whom the device was extracted within 7 days, the associated HR for death at 1 year was more than 40% lower (HR, 0.59; P < .001), reported Dr. Pokorney, who characterized these reductions as occurring in “a dose-response fashion.”

The very high risk of relapse despite antibiotics is the reason that “there is a class 1 indication for complete hardware removal,” Dr. Pokorney. He cited five studies that addressed this question. With partial device removal or medical therapy alone, relapse was consistently 50% or greater. In one study, it was 67%. In another it was 100%.

With complete removal, the rate of infection relapse was 1% or lower in four. In the fifth, the rate was 4.2%.

Infections can occur early or late after implantation, but cases accumulate over time. In the Medicare data sample, infection rates climbed from 0.3% at 1 year to 0.6% at 2 years and then to 1.1% at 3 years, Dr. Pokorney reported.

Other studies have also shown a steady increase in the proportion of implanted devices associated with infection over time. In a cohort study conducted in Olmstead County, Minnesota, the cumulative probability of a CIED infection reached 6.2% after 15 years and 11.7% after 25 years. While about half of these were infections localized to the device pocket, the others were potentially life-threatening systemic infections, according to Dr. Pokorney, who cited this study.

In his analysis of the Medicare data, all fee-for-service patients receiving a first CIED implant over a period of 14 years were included. The 14-year period ended just before the COVID-19 epidemic.

The more than 11,000 CIED infections were identified in 1,065,549 total CIED patients. Most (72%) had received a pacemaker. Of the others , more than half received an ICD and the others received a cardiac resynchronization device. The median age was 78 years.
 

Female and Black patients even less likely to undergo extraction

About half (49.1%) of the overall study population was female, but females represented only about 40% of those who developed an infection. Blacks represented just under 8% of the population but nearly 16% of the CIED infections. Both females and Blacks were significantly less likely than the overall study population to undergo extraction for their infection (P < .001 for both).

Perhaps predictably, patients with comorbidities were more likely to develop CIED infections. For example, 87% of those with infection, versus only 64.9% of the overall population, were in heart failure at the time of implantation. Diabetes (68.3% vs. 49.3%), ischemic heart disease (91.9% vs. 79.4%), renal disease (70.5% vs. 37.9%), and chronic obstructive pulmonary disease (70.6% vs. 55.0%) were also more common at baseline in those who went on to a CIED infection than in the overall population.

Based on the evidence that there is a large unmet need to improve adherence to the guidelines, Dr. Pokorney called for care pathways and other quality initiatives to address the problem.

The reasons that so many patients are not undergoing prompt device extraction at the time of infection is unclear, but Dr. Pokorney offered some hypotheses.

“There appears to be a false belief in the efficacy of antibiotics for treating CIED infections,” Dr. Pokorney said.
 

Comorbidities shouldn’t delay extraction

It is also possible that clinicians are concerned about performing extractions in patients with multiple comorbidities. If clinicians are delaying extractions for this reason, Dr. Pokorney suggested this behavior is misdirected given the fact that delays appear to increase mortality risk.

Several experts, including Rachel Lambert, MD, an electrophysiologist and professor of medicine at Yale University, New Haven, Conn., agreed that these data deserve a response.

“I was not surprised by the mortality data, but I was surprised at this low extraction rate,” said Dr. Lambert, who concurs with the guidelines. She indicated this study provides teeth to prompt action.

“It is great to have these data about the increased mortality risk to back up the guidelines,” she said.

More information is needed to understand exactly why CIED infection is not now leading to guideline-directed care. Dr. Pokorney said: “Where do we go from here is a key question.”

While several different types of initiatives might be needed, Dr. Pokorney called for regionalization of care to address the fact that not every center that places CIEDs has the capability to perform extractions.

“Extraction is not available at every center, and it probably should not be available at every center, so mechanisms are need to get patients with infection to the specialized centers that provide care,” he said.

Dr. Pokorney has financial relationships with Boston Scientific, Bristol-Myers Squibb, Gilead, Janssen, Medtronic, Pfizer, and Philips. Dr. Lambert reported financial relationships with Abbott, Amgen, and Medtronic.

In his analysis of the Medicare data, all fee-for-service patients receiving a first CIED implant over a period of 14 years were included. The 14-year period ended just before the COVID-19 epidemic.

The more than 11,000 CIED infections were identified in 1,065,549 total CIED patients. Most (72%) had received a pacemaker. Of the others , more than half received an ICD and the others received a cardiac resynchronization device. The median age was 78 years.
 

Female and Black patients even less likely to undergo extraction

About half (49.1%) of the overall study population was female, but females represented only about 40% of those who developed an infection. Blacks represented just under 8% of the population but nearly 16% of the CIED infections. Both females and Blacks were significantly less likely than the overall study population to undergo extraction for their infection (P < .001 for both).

Perhaps predictably, patients with comorbidities were more likely to develop CIED infections. For example, 87% of those with infection, versus only 64.9% of the overall population, were in heart failure at the time of implantation. Diabetes (68.3% vs. 49.3%), ischemic heart disease (91.9% vs. 79.4%), renal disease (70.5% vs. 37.9%), and chronic obstructive pulmonary disease (70.6% vs. 55.0%) were also more common at baseline in those who went on to a CIED infection than in the overall population.

Based on the evidence that there is a large unmet need to improve adherence to the guidelines, Dr. Pokorney called for care pathways and other quality initiatives to address the problem.

The reasons that so many patients are not undergoing prompt device extraction at the time of infection is unclear, but Dr. Pokorney offered some hypotheses.

“There appears to be a false belief in the efficacy of antibiotics for treating CIED infections,” Dr. Pokorney said.
 

Comorbidities shouldn’t delay extraction

It is also possible that clinicians are concerned about performing extractions in patients with multiple comorbidities. If clinicians are delaying extractions for this reason, Dr. Pokorney suggested this behavior is misdirected given the fact that delays appear to increase mortality risk.

Several experts, including Rachel Lambert, MD, an electrophysiologist and professor of medicine at Yale University, New Haven, Conn., agreed that these data deserve a response.

“I was not surprised by the mortality data, but I was surprised at this low extraction rate,” said Dr. Lambert, who concurs with the guidelines. She indicated this study provides teeth to prompt action.

“It is great to have these data about the increased mortality risk to back up the guidelines,” she said.

More information is needed to understand exactly why CIED infection is not now leading to guideline-directed care. Dr. Pokorney said: “Where do we go from here is a key question.”

While several different types of initiatives might be needed, Dr. Pokorney called for regionalization of care to address the fact that not every center that places CIEDs has the capability to perform extractions.

“Extraction is not available at every center, and it probably should not be available at every center, so mechanisms are need to get patients with infection to the specialized centers that provide care,” he said.

Dr. Pokorney has financial relationships with Boston Scientific, Bristol-Myers Squibb, Gilead, Janssen, Medtronic, Pfizer, and Philips. Dr. Lambert reported financial relationships with Abbott, Amgen, and Medtronic.

Most surgeons report being affected by performance anxiety in relation to their work, with the anxiety frequently having a negative effect on well-being, a new study of surgeons in the United Kingdom shows.

“Performance anxiety or stage fright is a widely recognized problem in music and sports, and there are many similarities between these arenas and the operating theater,” first author Robert Miller, MRCS, of the Surgical Psychology and Performance Group and the department of plastic and reconstructive surgery at St. George’s Hospital NHS Trust, London, said in an interview. “We were aware of it anecdotally in a surgical context, but for one reason or another, perhaps professional pride and fear of negative perception, this is rarely openly discussed amongst surgeons.”

In the cross-sectional study, published in Annals of Surgery, Dr. Miller and colleagues surveyed surgeons in all specialties working in the United Kingdom who had at least 1 year of postgraduate surgical training.

Of a total of 631 responses received, 523 (83%) were included in the analysis. The median age of those who responded was 41.2 years, and the mean duration of surgical experience was 15.3 years (range, 1-52 years). Among them, 62% were men, and 52% were of consultant/attending grade.

All of the respondents – 100% – said they believed that performance anxiety affected surgeons, 87% reported having experienced it themselves, and 65% said they felt that performance anxiety had an effect on their surgical performance.

Both male and female surgeons who reported experiencing performance anxiety had significantly worse mental well-being, as assessed using the Short Warwick Edinburgh Mental Wellbeing Scale, compared with those who did not have performance anxiety (P < .0001 for men and P < .001 for women).

Overall, however, male surgeons had significantly better mental well-being, compared with female surgeons (P = .003), yet both genders had significantly lower mental well-being scores compared with U.K. population norms (P = .0019 for men and P = .0001 for women).

The gender differences are “clearly an important topic, which is likely multifactorial,” Dr. Miller told this news organization. “The gender well-being gap requires more in-depth research, and qualitative work involving female surgeons is critical.”

Surgical perfectionism was significantly more common among respondents who did have performance anxiety in comparison with those who did not (P < .0001).

“Although perfectionism may be a beneficial trait in surgery, our findings from hierarchical multiple regression analysis also indicate that perfectionism, [as well as] sex and experience, may drive surgical performance anxiety and help predict those experiencing [the anxiety],” the authors noted.
 

Performing in presence of colleagues a key trigger

By far, the leading trigger that was identified as prompting surgeon performance anxiety was the presence – and scrutiny – of colleagues within the parent specialty. This was reported by 151 respondents. Other triggers were having to perform on highly complex or high-risk cases (66 responses) and a lack of experience (30 responses).

Next to planning and preparation, opening up and talking about the anxiety and shedding light on the issue was seen as a leading strategy to help with the problem, but very few respondents reported openly sharing their struggles. Only 9% reported that they had shared it openly; 27% said they had confided in someone, and 47% did not respond to the question.

“I wish we talked about it more and shared our insecurities,” one respondent lamented. “Most of my colleagues pretend they are living gods.”

Only about 45% of respondents reported a specific technique for overcoming their anxiety. In addition to being open about the problem, other techniques included self-care, such as exercise; and distraction outside of work to get perspective; relaxation techniques such as deep or controlled breathing; music; mindfulness; and positive self-statements.

About 9% said they had received psychological counseling for performance anxiety, and only 3% reported using medication for the problem.
 

Anxiety a positive factor?

Surprisingly, 70% of respondents reported feeling that surgical performance anxiety could have a positive impact on surgical performance, which the authors noted is consistent with some theories.

“This may be explained by the traditional bell-curve relationship between arousal and performance, which describes a dose-dependent relationship between performance and arousal until a ‘tipping point,’ after which performance declines,” the authors explained. “A heightened awareness secondary to anxiety may be beneficial, but at high doses, anxiety can negatively affect attentional control and cause somatic symptoms.”

They noted that “the challenge would be to reap the benefits of low-level stimulation without incurring possible adverse effects.”

Dr. Miller said that, in determining whether selection bias had a role in the results, a detailed analysis showed that “our respondents were not skewed to those with only high levels of trait anxiety.

“We also had a good spread of consultants versus trainees [about half and half], and different specialties, so we feel this is likely to be a representative sample,” he told this news organization.

That being said, the results underscore the need for increased awareness – and open discussion – of the issue of surgical performance anxiety.

“Within other professions, particularly the performing arts and sports, performance psychology is becoming an integral part of training and development,” Dr. Miller said. “We feel surgeons should be supported in a similar manner.

“Surgical performance anxiety is normal for surgeons at all levels and not something to be ashamed about,” Dr. Miller added. “Talk about it, acknowledge it, and be supportive to your colleagues.”
 

Many keep it to themselves in ‘prevailing culture of stoicism’

Commenting on the study, Carter C. Lebares, MD, an associate professor of surgery and director of the Center for Mindfulness in Surgery, department of surgery, University of California, San Francisco, said she was not surprised to see the high rates of performance anxiety among surgeons.

“As surgeons, no matter how hard we train or how thoroughly we prepare our intellectual understanding or the patient, the disease process, and the operation, there may be surprises, unforeseen challenges, or off days,” Dr. Lebares said.

“And whatever we encounter, we are managing these things directly under the scrutiny of others – people who can affect our reputation, operating privileges, and mental health. So, I am not surprised this is a prevalent and widely recognized issue.”

Dr. Lebares noted that the reluctance to share the anxiety is part of a “challenging and recognized conundrum in both medicine and surgery and is a matter of the prevailing culture of stoicism.

“We often are called to shoulder tremendous weight intraoperatively (having perseverance, self-confidence, or sustained focus), and in owning the weight of complications (which eventually we all will have),” she said.

“So, we do need to be strong and not complain, [but] we also need to be able to set that aside [when appropriate] and ask for help or allow others to shoulder the weight for a while, and this is not [yet] a common part of surgical culture.”

Dr. Lebares added that randomized, controlled trials have shown benefits of mindfulness interventions on burnout and anxiety.

“We have observed positive effects on mental noise, self-perception, conflict resolution, and resilience in surgical residents trained in mindfulness-based cognitive skills,” she said. “[Residents] report applying these skills in the OR, in their home lives, and in how they approach their training/education.”

The authors disclosed no relevant financial relationships. Dr. Lebares has developed mindfulness-based cognitive skills training for surgeons but receives no financial compensation for the activities.

A new subanalysis of the FAME 3 trial, which failed to show that percutaneous intervention (PCI) guided by fractional flow reserve (FFR) is noninferior to coronary artery bypass grafting (CABG) for treating three-vessel coronary artery disease, has associated PCI with early quality of life (QOL) advantages, according to findings presented at the annual scientific sessions of the American College of Cardiology.

Despite a modestly greater risk of major adverse cardiac events (MACE) at the end of 12 months’ follow-up among those treated with FFR-guided PCI, the greater QOL early after the procedure might be relevant to patients weighing these options, according to Frederik M. Zimmerman, MD, of Catharina Hospital in Eindhoven, the Netherlands.

“FFR-guided PCI results in a faster improvement in quality of life than CABG during the first year after revascularization, and it improved working status in patients younger than 65 years of age,” Dr. Zimmermann said.

The primary results of FAME 3 were presented at the 2021 Transcatheter Cardiovascular Therapeutics annual meeting by lead author William F. Fearon, MD, of Stanford (Calif.) University and published simultaneously in the New England Journal of Medicine.

Rather than confirming the hypothesis that FFR-guided PCI is comparable with CABG for the primary composite MACE outcome death from any cause, myocardial infarction, stroke, or revascularization, the incidence of MACE at 12 months was 10.6% in those randomized to PCI and 6.9% in the group assigned to CABG.

This translated into a hazard ratio for MACE of 1.5, signifying a 50% increase in risk for FFR-guided PCI relative to CABG for the primary outcome, a difference that negated the study definition of noninferiority (P = .35).

In this new health-related subanalysis, which was published simultaneously with his ACC presentation, the groups were compared over 12 months for QOL as measured with European Quality of Life–5 dimensions (EQ-5D) scale, angina as measured with the Canadian Cardiovascular Classification (CCC) system, and employment.

Outcomes data available in >85% of patients

Of the 1,500 patients enrolled and randomized in FAME 3 (757 to FFR-guided PCI and 743 to CABG), this health outcomes subanalysis was performed with complete data at 12 months from 89% of those in the PCI group and 88% of those in the CABG group.

Ultimately, the study did not show differences in any of these measures at the end of 12 months, but there were significant differences in QOL and employment at earlier time points. In particular, the significantly different (P < .001) trajectory for QOL improvement at 1 and 6 months favored FFR-guided PCI whether evaluated with the EQ-5D instrument or an EQ visual analog scale.

Rates of angina defined by as CCC class of at least 2 were low after revascularization in both arms of the study, negating any opportunity for differences, but patients aged younger than 65 years were almost twice as likely to have returned to full- or part-time work 1 month after revascularization (60.2% vs. 33.1%), and they remained at higher odds for working at 12 months (68.1% vs. 57.4%).

In patients aged older than 65 years, return-to-work rates did not differ significantly at any time point.

These results suggest potentially clinically meaningful early advantages for FFR-guided PCI, but some experts questioned the rationale for reporting positive secondary findings from a negative trial.

“This subanalysis is curious,” said Allen Jeremias, MD, director of interventional cardiology research, Saint Francis Hospital, Roslyn, N.Y. He pointed out that reporting these data is an anomaly.
 

Subanalyses uncommon in negative trials

“CABG was found to be better, so why look at QOL,” said Dr. Jeremias, who was an ACC-invited expert to discuss the results. However, he went on to say, “this could be an exception to the rule.”

The reason, according to Dr. Jeremias, is that the absolute difference at 12 months between FFR-guided PCI and CABG for the MACE events of greatest concern – death, MI, or stroke – was only about 2% greater in the FFR-guided PCI group (7.3% vs. 5.2%). The biggest contributor to the difference in MACE in FAME 3 at 12 months was the higher rate of repeat revascularization (5.9% vs. 3.9%).

Moreover, patients randomized to FFR-guided PCI had lower rates of many adverse events. This included risk of bleeding (1.6% vs. 3.8%; P = .009 as defined by type ≥3 Bleeding Academic Research Consortium , acute kidney injury (0.1% vs. 0.9%; P = .04), atrial fibrillation (2.4% vs. 14.1%; P < .001) and rehospitalization within 30 days (5.5% vs. 10.2%; P < .001).

In the context of a modest increase in risk of MACE and the lower rate of several important treatment-related adverse events, the QOL advantages identified in this subanalysis “might be a reasonable topic for patient-shared decision-making,” Dr. Jeremias suggested.
 

New data might inform patient decision-making

He granted the possibility that well-informed patients might accept the modestly increased risk of MACE for one or more of the outcomes, such as a higher likelihood of an early return to work, that favored FFR-guided PCI.

This is the point of this subanalysis, agreed Dr. Zimmermann.

“It is all about shared decision-making,” he said. Also emphasizing that the negative trial endpoint of FAME 3 “was driven largely by an increased risk of revascularization,” he believes that these new data might be a basis for discussions with patients weighing relative risks and benefits.

There are more data to come, according to Dr. Zimmermann, who said that follow-up of up to 5 years is planned. The 3-year data will be made available in 2023.

Dr. Zimmermann reported no potential conflicts of interest. Dr. Jeremias reported financial relationships with Abbott, ACIST, Boston Scientific, and Volcano. The investigator-initiated trial received research grants from Abbott Vascular and Medtronic.

These results suggest potentially clinically meaningful early advantages for FFR-guided PCI, but some experts questioned the rationale for reporting positive secondary findings from a negative trial.

“This subanalysis is curious,” said Allen Jeremias, MD, director of interventional cardiology research, Saint Francis Hospital, Roslyn, N.Y. He pointed out that reporting these data is an anomaly.
 

Subanalyses uncommon in negative trials

“CABG was found to be better, so why look at QOL,” said Dr. Jeremias, who was an ACC-invited expert to discuss the results. However, he went on to say, “this could be an exception to the rule.”

The reason, according to Dr. Jeremias, is that the absolute difference at 12 months between FFR-guided PCI and CABG for the MACE events of greatest concern – death, MI, or stroke – was only about 2% greater in the FFR-guided PCI group (7.3% vs. 5.2%). The biggest contributor to the difference in MACE in FAME 3 at 12 months was the higher rate of repeat revascularization (5.9% vs. 3.9%).

Moreover, patients randomized to FFR-guided PCI had lower rates of many adverse events. This included risk of bleeding (1.6% vs. 3.8%; P = .009 as defined by type ≥3 Bleeding Academic Research Consortium , acute kidney injury (0.1% vs. 0.9%; P = .04), atrial fibrillation (2.4% vs. 14.1%; P < .001) and rehospitalization within 30 days (5.5% vs. 10.2%; P < .001).

In the context of a modest increase in risk of MACE and the lower rate of several important treatment-related adverse events, the QOL advantages identified in this subanalysis “might be a reasonable topic for patient-shared decision-making,” Dr. Jeremias suggested.
 

New data might inform patient decision-making

He granted the possibility that well-informed patients might accept the modestly increased risk of MACE for one or more of the outcomes, such as a higher likelihood of an early return to work, that favored FFR-guided PCI.

This is the point of this subanalysis, agreed Dr. Zimmermann.

“It is all about shared decision-making,” he said. Also emphasizing that the negative trial endpoint of FAME 3 “was driven largely by an increased risk of revascularization,” he believes that these new data might be a basis for discussions with patients weighing relative risks and benefits.

There are more data to come, according to Dr. Zimmermann, who said that follow-up of up to 5 years is planned. The 3-year data will be made available in 2023.

Dr. Zimmermann reported no potential conflicts of interest. Dr. Jeremias reported financial relationships with Abbott, ACIST, Boston Scientific, and Volcano. The investigator-initiated trial received research grants from Abbott Vascular and Medtronic.

A new subanalysis of the FAME 3 trial, which failed to show that percutaneous intervention (PCI) guided by fractional flow reserve (FFR) is noninferior to coronary artery bypass grafting (CABG) for treating three-vessel coronary artery disease, has associated PCI with early quality of life (QOL) advantages, according to findings presented at the annual scientific sessions of the American College of Cardiology.

Despite a modestly greater risk of major adverse cardiac events (MACE) at the end of 12 months’ follow-up among those treated with FFR-guided PCI, the greater QOL early after the procedure might be relevant to patients weighing these options, according to Frederik M. Zimmerman, MD, of Catharina Hospital in Eindhoven, the Netherlands.

“FFR-guided PCI results in a faster improvement in quality of life than CABG during the first year after revascularization, and it improved working status in patients younger than 65 years of age,” Dr. Zimmermann said.

The primary results of FAME 3 were presented at the 2021 Transcatheter Cardiovascular Therapeutics annual meeting by lead author William F. Fearon, MD, of Stanford (Calif.) University and published simultaneously in the New England Journal of Medicine.

Rather than confirming the hypothesis that FFR-guided PCI is comparable with CABG for the primary composite MACE outcome death from any cause, myocardial infarction, stroke, or revascularization, the incidence of MACE at 12 months was 10.6% in those randomized to PCI and 6.9% in the group assigned to CABG.

This translated into a hazard ratio for MACE of 1.5, signifying a 50% increase in risk for FFR-guided PCI relative to CABG for the primary outcome, a difference that negated the study definition of noninferiority (P = .35).

In this new health-related subanalysis, which was published simultaneously with his ACC presentation, the groups were compared over 12 months for QOL as measured with European Quality of Life–5 dimensions (EQ-5D) scale, angina as measured with the Canadian Cardiovascular Classification (CCC) system, and employment.

Outcomes data available in >85% of patients

Of the 1,500 patients enrolled and randomized in FAME 3 (757 to FFR-guided PCI and 743 to CABG), this health outcomes subanalysis was performed with complete data at 12 months from 89% of those in the PCI group and 88% of those in the CABG group.

Ultimately, the study did not show differences in any of these measures at the end of 12 months, but there were significant differences in QOL and employment at earlier time points. In particular, the significantly different (P < .001) trajectory for QOL improvement at 1 and 6 months favored FFR-guided PCI whether evaluated with the EQ-5D instrument or an EQ visual analog scale.

Rates of angina defined by as CCC class of at least 2 were low after revascularization in both arms of the study, negating any opportunity for differences, but patients aged younger than 65 years were almost twice as likely to have returned to full- or part-time work 1 month after revascularization (60.2% vs. 33.1%), and they remained at higher odds for working at 12 months (68.1% vs. 57.4%).

The antifibrinolytic tranexamic acid (TXA) reduced serious bleeding without a significant effect on major vascular outcomes in patients undergoing noncardiac surgery at risk for these complications in the POISE-3 trial.

TXA cut the primary efficacy outcome of life-threatening, major, and critical organ bleeding at 30 days by 24% compared with placebo (9.1% vs. 11.7%; hazard ratio [HR], 0.76; P < .0001).

The primary safety outcome of myocardial injury after noncardiac surgery (MINS), nonhemorrhagic stroke, peripheral arterial thrombosis, and symptomatic proximal venous thromboembolism (VTE) at 30 days occurred in 14.2% vs.. 13.9% of patients, respectively (HR, 1.023). This failed, however, to meet the study›s threshold to prove TXA noninferior to placebo (one-sided P = .044).

There was no increased risk for death or stroke with TXA, according to results published April 2 in the New England Journal of Medicine.

Principal investigator P.J. Devereaux, MD, PhD, Population Health Research Institute and McMaster University, Hamilton, Ontario, Canada, pointed out that there is only a 4.4% probability that the composite vascular outcome hazard ratio was above the noninferiority margin and that just 10 events separated the two groups (649 vs.. 639).

“Healthcare providers and patients will have to weigh a clear beneficial reduction in the composite bleeding outcome, which is an absolute difference of 2.7%, a result that was highly statistically significant, versus a low probability of a small increase in risk of the composite vascular endpoint, with an absolute difference of 0.3%,” a nonsignificant result, Dr. Devereaux said during the formal presentation of the results at the hybrid annual scientific sessions of the American College of Cardiology.

The findings, he said, should also be put in the context that 300 million adults have a major surgery each year worldwide and most don’t receive TXA. At the same time, there’s an annual global shortage of 30 million blood product units, and surgical bleeding accounts for up to 40% of all transfusions.

“POISE-3 identifies that use of TXA could avoid upwards of 8 million bleeding events resulting in transfusion on an annual basis, indicating potential for large public health and clinical benefit if TXA become standard practice in noncardiac surgery,” Dr. Devereaux said during the late-breaking trial session.

TXA is indicated for heavy menstrual bleeding and hemophilia and has been used in cardiac surgery, but it is increasingly being used in noncardiac surgeries. As previously reported, POISE showed that the beta-blocker metoprolol lowered the risk for myocardial infarction (MI) but increased the risk for severe stroke and overall death, whereas in POISE-2, perioperative low-dose aspirin lowered the risk for MI but was linked to more major bleeding.

The cumulative data have not shown an increased risk for thrombotic events in other settings, Dr. Devereaux told this news organization.

“I’m a cardiologist, and I think that we’ve been guilty at times of always only focusing on the thrombotic side of the equation and ignoring that bleeding is a very important aspect of the circulatory system,” he said. “And I think this shows for the first time clear unequivocal evidence that there’s a cheap, very encouraging, safe way to prevent this.”

“An important point is that if you can give tranexamic acid and prevent bleeding in your cardiac patients having noncardiac surgery, then you can prevent the delay of reinitiating their anticoagulants and their antiplatelets after surgery and getting them back on the medications that are important for them to prevent their cardiovascular event,” Dr. Devereaux added.

Discussant Michael J. Mack, MD, commented that TXA, widely used in cardiac surgery, is an old, inexpensive drug that “should be more widely used in noncardiac surgery.” Dr. Mack, from Baylor Scott & White Health, Dallas, added that he would limit it to major noncardiac surgery.

International trial

PeriOperative ISchemic Evaluation-3 (POISE-3) investigators at 114 hospitals in 22 countries (including countries in North and South America, Europe, and Africa; Russia; India; and Australia) randomly assigned 9,535 patients, aged 45 years or older, with or at risk for cardiovascular and bleeding complications to receive a TXA 1-g intravenous bolus or placebo at the start and end of inpatient noncardiac surgery.

Patients taking at least one long-term antihypertensive medication were also randomly assigned to a perioperative hypotension- or hypertension-avoidance strategy, which differ in the use of antihypertensives on the morning of surgery and the first 2 days after surgery, and in the target mean arterial pressure during surgery. Results from these cohorts will be presented in a separate session on April 4.

The study had planned to enroll 10,000 patients but was stopped early by the steering committee because of financial constraints resulting from slow enrollment during the pandemic. The decision was made without knowledge of the trial results but with knowledge that aggregate composite bleeding and vascular outcomes were higher than originally estimated, Dr. Devereaux noted.

Among all participants, the mean age was 70 years, 56% were male, almost a third had coronary artery disease, 15% had peripheral artery disease, and 8% had a prior stroke. About 80% were undergoing major surgery. Adherence to the study medications was 96.3% in both groups.

Secondary bleeding outcomes were lower in the TXA and placebo groups, including bleeding independently associated with mortality after surgery (8.7% vs. 11.3%), life-threatening bleeding (1.6% vs. 1.7%), major bleeding (7.6% vs. 10.4%), and critical organ bleeding (0.3% vs. 0.4%).

Importantly, the TXA group had significantly lower rates of International Society on Thrombosis and Haemostasis major bleeding (6.6% vs. 8.7%; P = .0001) and the need for transfusion of 1 or more units of packed red blood cells (9.4% vs. 12.0%; P <.0001), Dr. Devereaux noted.

In terms of secondary vascular outcomes, there were no significant differences between the TXA and placebo groups in rates of MINS (12.8% vs. 12.6%), MINS not fulfilling definition of MI (both 11.5%), MI (1.4% vs. 1.1%), and the net risk-benefit outcome (a composite of vascular death and nonfatal life-threatening, major, or critical organ bleeding, MINS, stroke, peripheral arterial thrombosis, and symptomatic proximal VTE; 20.7% vs. 21.9%).

The two groups had similar rates of all-cause (1.1% vs. 1.2%) and vascular (0.5% vs. 0.6%) mortality.

There also were no significant differences in other tertiary outcomes, such as acute kidney injury (14.1% vs. 13.7%), rehospitalization for vascular reasons (1.8% vs. 1.6%), or seizures (0.2% vs. <0.1%). The latter has been a concern, with the risk reported to increase with higher doses.

Subgroup analyses

Preplanned subgroup analyses showed a benefit for TXA over placebo for the primary efficacy outcome in orthopedic and nonorthopedic surgery and in patients with hemoglobin level below 120 g/L or 120 g/L or higher, with an estimated glomerular filtration rate less than 45 mL/min/1.73 m ²  or 45 mL/min/1.73 m ²  or higher, or with an N-terminal pro– B-type natriuretic peptide level below 200 ng/L or 200 ng/L or higher.

For the primary safety outcome, the benefit favored placebo but the interaction was not statistically significant for any of the four subgroups.

A post hoc subgroup analysis also showed similar results across the major categories of surgery, including general, vascular, urologic, and gynecologic, Dr. Devereaux told this news organization.

Although TXA is commonly used in orthopedic procedures, Dr. Devereaux noted, in other types of surgeries, “it’s not used at all.” But because TXA “is so cheap, and we can apply it to a broad population, even at an economic level it looks like it’s a winner to give to almost all patients having noncardiac surgery.”

The team also recently published a risk prediction tool that can help estimate a patient’s baseline risk for bleeding.

“So just using a model, which will bring together the patient’s type of surgery and their risk factors, you can look to see, okay, this is enough risk of bleeding, I’m just going to give tranexamic acid,” he said. “We will also be doing economic analyses because blood is also not cheap.”

The study was funded by the Canadian Institutes of Health Research, National Health and Medical Research Council (Australia), and the Research Grant Council (Hong Kong).

The two groups had similar rates of all-cause (1.1% vs. 1.2%) and vascular (0.5% vs. 0.6%) mortality.

There also were no significant differences in other tertiary outcomes, such as acute kidney injury (14.1% vs. 13.7%), rehospitalization for vascular reasons (1.8% vs. 1.6%), or seizures (0.2% vs. <0.1%). The latter has been a concern, with the risk reported to increase with higher doses.

Subgroup analyses

Preplanned subgroup analyses showed a benefit for TXA over placebo for the primary efficacy outcome in orthopedic and nonorthopedic surgery and in patients with hemoglobin level below 120 g/L or 120 g/L or higher, with an estimated glomerular filtration rate less than 45 mL/min/1.73 m ²  or 45 mL/min/1.73 m ²  or higher, or with an N-terminal pro– B-type natriuretic peptide level below 200 ng/L or 200 ng/L or higher.

For the primary safety outcome, the benefit favored placebo but the interaction was not statistically significant for any of the four subgroups.

A post hoc subgroup analysis also showed similar results across the major categories of surgery, including general, vascular, urologic, and gynecologic, Dr. Devereaux told this news organization.

Although TXA is commonly used in orthopedic procedures, Dr. Devereaux noted, in other types of surgeries, “it’s not used at all.” But because TXA “is so cheap, and we can apply it to a broad population, even at an economic level it looks like it’s a winner to give to almost all patients having noncardiac surgery.”

The team also recently published a risk prediction tool that can help estimate a patient’s baseline risk for bleeding.

“So just using a model, which will bring together the patient’s type of surgery and their risk factors, you can look to see, okay, this is enough risk of bleeding, I’m just going to give tranexamic acid,” he said. “We will also be doing economic analyses because blood is also not cheap.”

The study was funded by the Canadian Institutes of Health Research, National Health and Medical Research Council (Australia), and the Research Grant Council (Hong Kong). Dr. Devereaux reports research/research grants from Abbott Diagnostics, Philips Healthcare, Roche Diagnostics, and Siemens. Dr. Mack reports receiving research grants from Abbott Vascular, Edwards Lifesciences, and Medtronic.

Five international cardiac surgery associations have banded together to address “substantive concerns” regarding the recently updated Valve Academic Research Consortium 3 (VARC-3) clinical endpoint definitions for aortic valve research.

The VARC-3 update was a multidisciplinary effort that included more than a dozen new or modified definitions for use in transcatheter and surgical aortic valve replacement (TAVR/SAVR) clinical trials, but drew criticism last year from surgeons that some of its definitions favor TAVR over surgery and that its writing committee had deep ties to industry and lacked diversity.

The new surgical associations’ position statement calls out five specific VARC-3 definitions – rehospitalization, valve thrombosis, bleeding, myocardial infarction (MI), and left bundle-branch block (LBBB).

The statement was jointly issued by the Society of Thoracic Surgeons (STS), the American Association for Thoracic Surgery, the European Association for Cardio-Thoracic Surgery, the Asian Society for Cardiovascular and Thoracic Surgery, and the Latin American Association of Cardiac and Endovascular Surgery.

It was copublished in Annals of Thoracic Surgery, the Journal of Thoracic and Cardiovascular Surgery, the European Journal of Cardio-Thoracic Surgery, and the Asian Cardiovascular and Thoracic Annals.

“We hope that this message can be seen, even if it’s somewhat difficult to hear sometimes, as positive constructive criticism compared to some of the dialogue that we’ve had on social media,” lead author Patrick O. Myers, MD, Lausanne (Switzerland) University Hospital, said in an interview. “It’s not criticizing people or the process but just trying to make these definitions better to ensure the good design of clinical trials.”

The president of each surgical association recommended representatives to help write the position statement, and once completed over Zoom meetings, it received formal endorsement from each association prior to publication, he said.

Reached for comment, VARC-3 lead author Philippe Généreux, MD, Gagnon Cardiovascular Institute, Morristown (N.J.) Medical Center, said, “I was pleasantly surprised that their comments were actually pretty minor and that most of these comments are really more a reflection, not of the validity of the definitions, but rather their applications.”

He noted that all the potential issues with the definitions were already discussed during the making of VARC-3 and resolved by consensus of more than 50 experts including the STS president at the time, Food and Drug Administration officials, and experts from the community.

“To be quite honest, I’m not sure they have consensus,” Dr. Généreux said. He added that the writing committee welcomes input from anyone, but “we’re not going to change the definitions to please eight individuals if we strongly believe by consensus of experts in the field that this is not the right thing to do.”

Rehospitalizations and valve thrombosis

The surgical associations praise VARC-3 for providing a standardized definition of bioprosthetic valve failure, but say they will not endorse the inclusion of rehospitalization as a component of the primary efficacy composite endpoint along with all-cause mortality, stroke, and quality of life.

They note that rehospitalizations outnumber mortality events, especially in short follow-up trials, and that the superiority of TAVR at 1 year in the PARTNER 3 trial of low-risk patients was driven primarily by more rehospitalizations in the surgical arm, but that this superiority was waning at 2 years of follow-up.

“The first thing we are calling for is that it shouldn’t be part of the primary composite outcome measure,” Dr. Myers said. But if it really has to be included, a 30-day blanking period for rehospitalization “would acknowledge that there’s a greater risk of rehospitalization during the acute phase of recovering from surgery.”

Dr. Généreux said that VARC-3 provides granular details for defining the different types of hospitalizations, but that a 30-day blanking period makes no sense. “If you close your eyes to anything within 30 days because you don’t like it, you’re missing the opportunity to improve your procedure, to improve your treatment, and to characterize precisely what happened with your patient.”

The new document lauds VARC-3’s focus on patient-centered and clinically relevant endpoints but questions the definition of valve thrombosis as a “clinically significant” thrombus. It points out that the incidence of valve thrombosis was significantly higher with TAVR versus SAVR in PARTNER 3 using the older VARC-2 definition, which did not require evidence of clinical sequelae (2.6% vs. 0.7%; P = .02). Under the new definition, however, half of the thrombi would be relabeled as “nothing there,” Dr. Myers said.

“As we’re doing this in younger and younger patients who will survive longer, there is a question of thrombus having an effect on the valve and leading to earlier structural valve deterioration,” he added. “All this is conjecture. We don’t have the data. So mainly what we’re advocating is that all thrombi should be reported.”
 

MIs, bleeding, and LBBB

The policy statement also criticizes VARC-3’s decision to define periprocedural (type 5) MI using a biomarker-only definition without need of clinical confirmation. Such definitions have been shown to have a very poor prognostic significance in surgical series compared with the Universal Definitions of Myocardial Infarction, Dr. Myers said.

“What’s interesting is that for thrombus and bleeding, they require clinical correlation, but on the perioperative MI they now use a definition that does not require clinical significance, meaning no ECG changes, no regional wall motion abnormalities or things like that,” he observed.

The decision also seems to disregard the EXCEL trial controversy that illustrated how outcomes and a trial’s message can change depending on which definition of periprocedural MI is used.

With regard to bleeding, the surgical associations agree with the VARC-3 recommendation to use different thresholds when bleeding is integrated into a composite endpoint (type 2 or greater for TAVR and types 3 or greater for SAVR) but suggest this important point should be featured in the chapter on bleeding rather than the section on composite endpoints.

The surgical associations say VARC-3 also got it right adding the need for a new permanent pacemaker to the early composite safety endpoint, but that it was a “missed opportunity” not to include new left bundle-branch block in the safety composite, despite recognizing that this may become an important endpoint to consider in the future.

Dr. Myers said that left bundle-branch block could have implications for survival as TAVR moves into lower-risk, younger patients, as some data with 1-year follow-up suggest it has a prognostic impact, even in the higher-risk older patients with more competing risks.

Finally, the surgical associations point out that only two of the 23 VARC-3 authors were practicing cardiac surgeons and say that a more diverse writing group “may help mitigate issues related to the duality of interests.”

Dr. Généreux said that the final author list is not a reflection of the rigorous work done by 11 cardiac surgeons including the two surgeon authors. The VARC-3 writing committee also had a good representation of women, unlike the surgical position statement, which was penned by eight men.

Dr. Myers reported no relevant financial relationships. Coauthors disclosed ties with EACTS, Edwards Lifesciences, Medtronic, Abbott Vascular, Boston Scientific, CryoLife, Shockwave, and JenaValve. Dr. Généreux disclosed ties with Abbott Vascular, Abiomed, Boston Scientific, Cardinal Health, Cardiovascular Systems, Edwards Lifesciences, Medtronic, Opsens, Siemens, SoundBite Medical Solutions, Sig.Num, Saranas, Teleflex, Tryton Medical, Pi-Cardia, and Puzzle Medical.
