Clinical efficacy of direct or indirect left ventricular unloading during venoarterial extracorporeal membrane oxygenation for primary cardiogenic shock.

ABSTRACT:

Objective

Left ventricular (LV) distention is a feared complication in patients receiving venoarterial (VA) extracorporeal membrane oxygenation (ECMO). LV unloading can be achieved indirectly with intra-aortic balloon pump (IABP) or directly with an Impella device (Abiomed, Danvers, Mass). We sought to assess the clinical and hemodynamic effects of IABP and Impella devices on patients supported with VA ECMO.

Methods

We conducted a retrospective review of VA ECMO patients at our institution from January 2015 to June 2020. Patients were categorized as either ECMO alone or ECMO with LV unloading. LV unloading was characterized as either ECMO with IABP or ECMO with Impella. We recorded baseline characteristics, survival, complications, and hemodynamic changes associated with dev
