Concomitant Implantation of Impella® on Top of Veno-Arterial Extracorporeal Membrane Oxygenation May Improve Survival of Patients with Cardiogenic Shock

AIMS: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support stabilizes patients with cardiogenic shock. Despite improved oxygenation and peripheral circulation, LV unloading may be impeded due to the increased afterload, resulting in a failing static left ventricle and in high mortality. METHODS AND RESULTS: compared with patients with VA-ECMO only. We retrospectively collected data on patients from two tertiary critical care referral centres. We enrolled 157 patients treated with VA-ECMO from January 2013 to April 2015: 123 received VA-ECMO support and 34 had concomitant treatment with VA-ECMO and Impella. A propensity-matching analysis was performed in a 2:1 ratio, resulting in 42 patients…
