Management of ECPELLA during mitral valve replacement in patients with
cardiogenic shock due to post-infarct papillary muscle rupture.
Abstract
Papillary muscle rupture is a fatal complication with a high operative
mortality rate of 13–40%. Most patients experience cardiogenic shock
and hypoxia due to pulmonary edema caused by severe mitral
regurgitation. Although preoperative stabilization using a mechanical
assist device potentially improves surgical outcomes, an appropriate
strategy has not yet been established. ECPELLA is a useful mechanical
circulatory support (MCS) strategy, combining venoarterial
extracorporeal membrane oxygenation and Impella®, and potentially
increases cardiac output and tissue perfusion and improves left
ventricular distension and oxygenation in patients with refractory
cardiogenic shock. Herein, we present our surgical technique involving
the successful management of ECPELLA during surgery in patients with
papillary muscle rupture.
