Impella (R) pumps are increasingly utilized in patients in cardiogenic shock. We report on a case series where Impella support was insufficient, and a switch to venoarterial extracorporeal membrane oxygenation (VA ECMO) became necessary. ECMO patients with previous Impella devices were identified utilizing our institutional ECMO database. Since 2014, 10 patients with a mean age of 62 +/- 3 years were identified. Despite correct placement of all Impella pumps, cardiogenic shock persisted with progressive multi-organ failure (Impella type 2.5/CP n=6/4 patients). Femoro-femoral VA ECMO was implanted percutaneously on the contralateral side with the Impella initially left on standby but retracted into the descending aorta for transport reasons after a mean support time of 20 +/- 8 h. All patients were able to unload their heart by left ventricular ejection with a blood pressure amplitude of 15 +/- 3 mmHg on VA ECMO support. After VA ECMO implantation haemodynamic parameters improved significantly within 24 h of support (mean serum lactate levels decreased from 92 +/- 17 to 44 +/- 10 mg/dl, P = 0.031). Survival to hospital discharge was 70%. These data indicate that the Impella 2.5 (R) and CP (R) might not be sufficient in profound cardiogenic shock. Comparative studies are necessary to specify which patient population benefits from which type of circulatory support.
