Prognostic Implication of RV Coupling to Pulmonary Circulation for Successful Weaning From Extracorporeal Membrane Oxygenation.
The aim of this study was to explore if right ventricular (RV) contractile function and its coupling to pulmonary circulation (PC) were associated with successful weaning from venoarterial-extracorporeal membrane oxygenation (VA-ECMO) at maintenance of pump flow. ⋯ Echocardiographic RV-PC coupling metrics exhibited a significantly better performance for predicting successful weaning from VA ECMO compared with conventional echocardiographic criteria at maintenance of pump flow.

Noninvasive Hemodynamic Assessment of Shock Severity and Mortality Risk Prediction in the Cardiac Intensive Care Unit.
This study sought to define the 2-dimensional and Doppler echocardiographic hemodynamics associated with each Society for Cardiovascular Angiography and Interventions (SCAI) stage, and to determine their association with mortality. ⋯ Noninvasive 2-dimensional and Doppler echocardiographic parameters correlate with the SCAI shock stages and improve risk stratification for hospital mortality in CICU patients. Low stroke volume index and high E/e' ratio demonstrated the strongest association with hospital mortality.

Observational StudyPrognostic Value of Right Ventricular Longitudinal Strain in Patients With COVID-19.
The aim of this study was to investigate whether right ventricular longitudinal strain (RVLS) was independently predictive of higher mortality in patients with coronavirus disease-2019 (COVID-19). ⋯ RVLS is a powerful predictor of higher mortality in patients with COVID-19. These results support the application of RVLS to identify higher risk patients with COVID-19.
