Video Summary

In this lecture, the speaker discusses the use of point-of-care ultrasonography (POCUS) in screening shock patients who require mechanical circulatory support. They describe a contemporary POCUS framework in critical care medicine and compare the diagnostic accuracy of qualitative and quantitative echocardiographic assessment for left and right systolic ventricular dysfunction. The speaker explains four parameters for estimating left ventricular systolic function: longitudinal shortening, anterior mitral leaflet motion, thickening of wall segments, and change in area of cavity. They also present five echocardiographic measures for evaluating right ventricular systolic function, including the ratio of right and left ventricular end diastolic area, apex forming ventricle, tricuspid and mitral annulus motion, right ventricular free wall hypokinesis, and flattening of the interventricular septum. The lecture concludes by stating that POCUS can be used as a valid screening tool in the initial management and treatment of shock patients.

Asset Caption

The incidence of cardiogenic shock is increasing. In the hopes of improving outcomes, clinicians are increasingly turning to percutaneous left and right mechanical circulatory support devices. The widespread availability of these devices and a multidisciplinary approach that combines expertise from cardiologists, heart failure specialists, cardiac surgeons, and critical care specialists may help pair the right patient with the right device at the right time. Echocardiography is essential in all advanced hemodynamic support stages in the adult and pediatric ICU. This session will demonstrate the most relevant echocardiographic features in the initial assessment, continuous monitoring, and recognition of complications that the critical care team can face at any time with commercially available devices— venoarterial extracorporeal membrane oxygenation, intra-aortic balloon pump counterpulsation, various heart pump system models, and percutaneous left ventricular devices in adult and pediatric patients with shock. Experts in the field will provide the most practical didactics for immediate clinical practice application.
