Advanced critical care echocardiography: A noninvasive tool for hemodynamic assessment in critically ill patients
Hemodynamic assessments in critically ill patients are important to guide accurate management; however, traditional invasive methods of measuring cardiac output have significant limitations, including risks of infection and bleeding. ACCE can provide a multitude of hemodynamic measurements from cardiac output (CO) to right ventricular systolic pressure (RVSP) and left atrial pressure (LAP). Combinations of left ventricular function parameters, along with estimation of filling pressures, can help distinguish between types of shock. Schmidt and colleagues (Sci Rep. 2022;12[1]:7187) demonstrated that measurement of these indices in the majority of patients helped elucidate the cause for hemodynamic compromise. They found presence of a cardiac index (CI) < 2.5/min.m2 was associated with a doubling of ICU mortality as compared with predictions based on severity of illness scores in otherwise hemodynamically stable patients. Hollenberg and colleagues (Am J Cardiol. 2021;153:135-39) demonstrated the feasibility of a simpler stratification using the left ventricular ejection fraction (LVEF) and CI in coronavirus disease 2019 patients with shock, where low CI despite having a preserved LVEF was associated with worse outcomes.
Quick, reliable data are an intensivist’s friend. Utilizing ACCE at the bedside adds another tool in our arsenal to provide real-time hemodynamic data that can be used to manage patients in the ICU. ACCE also allows repeated measurements to determine changes based on therapeutic interventions initiated.
In recognition of the importance of ACCE as a tool for intensivists, the National Board of Echocardiography (NBE) now offers a pathway toward board certification with the Examination of Special Competence in Critical Care Echocardiography (CCEeXAM). CHEST continues to offer cutting-edge courses in ACCE, as well as a board review course for learners interested in sitting for the CCEeXAM.
