Degree of change in right ventricular adaptation measures during axillary Impella support informs risk stratification for early, severe right heart failure following durable LVAD implantation

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...
