    ..Late RHF is common after continuous-flow LVAD implantation, but does not affect survival during LVAD support. However, it is associated with worse overall outcomes in the BTT population. ..

    ..03). The 3-year post-transplant survival was 41% in the VAD group and 66% in the VA-ECMO group (p = 0.13). For severe PGD, support with VA-ECMO appears to result in better clinical outcomes compared with VAD. ..
