Liberal use of veno-arterial extracorporeal membrane oxygenation in combined sequential heart-liver transplantation

Abstract

Combined heart-liver transplantation (CHLT) is a rarely though increasingly performed procedure with evolving indications. Despite CHLT being performed at only a handful of centers, the use of intraoperative mechanical circulatory support to optimize hemodynamics and facilitate dual-organ transplantation varies widely. At our center, we liberally utilize veno-arterial extracorporeal membrane oxygenation (V-A ECMO) when a veno-venous shunt is anticipated to be insufficient in mitigating the hemodynamic perturbations associated with liver reperfusion. In this series, we describe our experience with V-A ECMO in sequential (heart-first) CHLT and demonstrate highly favorable outcomes with this strategy.
