Abstract

Purpose To describe the outcome of VAD implantation with respect to the clinical status and the presence of temporary mechanical circulatory support (tMCS) prior to VAD implantation. Methods We analysed all patients from the EUROMACS database, with 1-year follow-up analysis and included 2571 patients. 2008 patients had no tMCS prior to implantation of a durable device and 995 of those received inotropic support. Out of the 563 patients bridged by tMCS, 310 were supported by intraaortic balloon pump (IABP) and 334 by extracorporeal life support (ECLS), 81 patients were bridge by ECLS+IABP. Results Median age was 56 (IQR 47-62), 17.8% were female, 16.9% were intubated and 8% underwent prior CPR. Patients with tMCS were younger (54 vs.56 years, p=0.001) and had a higher rate of previous cardiac surgery (22.9 vs. 12.4%, p Conclusion Patients with tMCS prior to VAD implantation have a higher one-year mortality compared to patients without MCS. The presence of tMCS prior to implantation of a VAD within the EUROMACS database cohort is an independent predictor of one-year mortality. However other variables such as tricuspid regurgitation, low hemoglobin, low platelet counts and more than 3 inotropes predicted one-year mortality even to a higher extend.
