Observational StudyLeft Ventricular Ejection Fraction Correlation With Stroke Volume as Estimated by Doppler Echocardiography in Cardiogenic Shock: A Retrospective Observational Study.
Echocardiography is the main tool for cardiac assessment and helps to guide management in patients admitted to the intensive care unit (ICU) with cardiogenic shock (CS). Left ventricular ejection fraction (LVEF) is a commonly used echocardiographic surrogate for left ventricular (LV) systolic function. In this hypothesis-generating study, the authors investigated the correlation between LVEF and stroke volume (SV)/SV index (SVI) estimated by Doppler echocardiography in patients admitted to the ICU with CS and reduced LVEF. ⋯ There is a weak correlation between LVEF and SV or SVI estimated by Doppler echocardiography in patients admitted to the ICU with STEMI complicated by CS and reduced LVEF. Visually estimated LVEF correlated slightly better with Doppler SV compared to modified Simpson's LVEF.

ReviewThe role of extracorporeal membrane oxygenation in COVID-19.
An extracorporeal membrane oxygenation (ECMO) program is an important component in the management of patients with COVID-19, but it is imperative to implement a system that is well-supported by the institution and staffed with well-trained clinicians to both optimize patient outcomes and to keep providers safe. There are many unknowns related to COVID-19, and one of the most challenging aspects for clinicians is the lack of predictive knowledge as to why some patients fail medical therapy and require advanced support such as ECMO. ⋯ As this pandemic continues, it will be important to compile and analyze multicentered data pertaining to patient-specific outcomes to help guide clinicians caring for patients with COVID-19 undergoing ECMO support. In this paper, the authors demonstrate the strategies utilized by a major quaternary care center in the utilization and management of ECMO for patients with COVID-19.
