Protracted aortic valve closure during peripheral veno-arterialextracorporeal life support: is intra-aortic balloon pump an effectivesolution?

摘要

Background:Left ventricular (LV) afterload increase with protracted aortic valve (AV) closure may represent a complication of veno-arterial extracorporeal membrane oxygenation (V-A ECMO). The aim of the present study was to assess the effects of an intra-aortic balloon pump (IABP) to overcome such a hemodynamic shortcoming in patients submitted to peripheral V-A ECMO.
