Huang KC, et al. - An assessment was performed of three-dimensional echocardiography (3DE)-derived right ventricular (RV) ejection fraction (RVEF) in patients with refractory cardiogenic shock stabilized by venoarterial extracorporeal membrane oxygenation (VA-ECMO). Researchers, in addition, explored the association between 3DE-derived RVEF and weaning success as well as the prognosis after the first intent of decannulation. They realized that three-dimensional echocardiography–derived RVEF might represent the composite results of RV contractility, left ventricular performance, and fluid status. Under mechanical circulatory support of VA-ECMO, RVEF > 24.6% seemed correlated with higher weaning success and lower 30-day mortality after the first intent of decannulation.
