Dynamic left ventricular outflow tract obstruction in critical illness: etiology-driven management and the role of bedside transthoracic echocardiography

Key Points

Management of LVOTO improves patient outcomes in critical care settings, emphasizing timely interventions.
Nearly all hypotensive patients in ICUs should undergo bedside transthoracic echocardiography for rapid diagnosis.
Bedside echocardiography is essential for guiding targeted interventions in life-threatening LVOTO cases.
Implementation as standard of care may enhance treatment effectiveness by identifying underlying causes.

Abstract

LVOTO is a life-threatening yet underrecognized complication in critical care, requiring prompt and tailored management based on its diverse etiologies. Bedside TTE serves as an essential tool for rapid diagnosis, guiding targeted interventions, and optimizing outcomes in these high-risk patients. It should be stressed that almost all hypotensive patients in contemporary ICUs should receive bedside TTE as a standard of care, given its critical role in identifying underlying causes and informing timely treatment decisions.
