Résumé
Risk assessment for early, severe right heart failure (RHF) after LVAD implantation remains imperfect. We sought to define the differences in RV adaptation and load after axillary Impella support between patients who experienced RHF and those who did not. Seventeen of 18 patients included were deemed intermediate or high risk for RHF by EUROMACS-RHF score. Before Impella insertion, RV adaptation parameters (RAP, RAP:PCWP, PAPi) were worse in the non-RHF group compared to the RHF group. In both groups, RV load parameters (effective pulmonary arterial elastance, pulmonary vascular resistance, and pulmonary vascular compliance) improved after Impella insertion. Lesser improvements in RV adaptation were seen in the RHF group. Moreover, load-to-adaptation relationships (E
