Early right ventricular (RV) failure after insertion of an implantable left ventricular assist device (LVAD) is associated with a poor prognosis and increased mortality. Improved assessment of RV volumes with cardiovascular magnetic resonance imaging (CMR) prior to LVAD placement may lead to more optimal patient selection.
Patients were referred for cardiovascular magnetic resonance imaging prior to LVAD placement. We assessed the association of mortality to pre-LVAD right ventricular end systolic volume index (RVESVI), right ventricular end diastolic volume index (RVEDVI), left ventricular ejection fraction (LVEF) by CMR. Right ventricular stroke work index (RVSWI) was determined by pre-LVAD right heart catheterization.

Increased RVESVI and RVEDVI assessed by CMR prior to implantation of LVADs is a predictor of post-implant mortality, while more typical measures such as LVEF was not. CMR acquisition and RV image quality was not hindered by implantable cardiac devices. Evaluation of RV volumes by CMR may improve risk-stratification and further refine patient selection for LVAD implantation.
