Use of Transcarotid IMPELLA 2.5 Axial-Flow Pump Device for Left Ventricle Unloading During VA-ECMO Support in Pediatric Acute Heart Failure

Abstract

An alternative strategy for left ventricular (LV) venting during short-term mechanical circulatory support is use of Impella axial-flow pump. We present our transcarotid Impella 2.5 implantation technique using a polytetrafluoroethylene graft, in two children with acute heart failure treated primarily with venoarterial ECMO. The venoarterial extracorporeal membrane oxygenator and Impella support were maintained for 5 and 17 days, respectively. Transcarotid Impella implantation might be an alternative and feasible option in pediatrics patients affected by severe LV failure, as a bridge to decision or bridge to candidacy. Potentially, the Impella 2.5 device provides less invasive support for children with heart failure.
