Multicenter StudyEchocardiographic Predictors of Successful Extracorporeal Membrane Oxygenation Weaning After Refractory Cardiogenic Shock.
Limited data are available regarding echocardiographic predictors for successful weaning from venoarterial (VA) extracorporeal membrane oxygenation (ECMO). We sought to determine whether echocardiographic parameters during ECMO flow study could predict successful weaning from ECMO. ⋯ Improvement of lateral e' velocity and tricuspid annular S' velocity during VA-ECMO flow study may better represent cardiac reserve from a recovering heart than conventional echocardiographic parameters at minimal flow. Assessment of tissue Doppler parameters during ECMO flow study is a simple and feasible method to guide physicians on the optimal time to wean from ECMO.
