Abstract
Methods 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 preLVAD right heart catheterization.
Highlights
Right ventricular (RV) failure after insertion of an implantable left ventricular assist device (LVAD) is associated with a poor prognosis and increased mortality
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 cardiovascular magnetic resonance imaging (CMR)
We studied 15 consecutive patients who received HVAD (60%) and HeartMate II (40%) LVADs for a diagnosis of dilated cardiomyopathy (57%) and ischemic cardiomyopathy (43%). 26.7% of patients had an implantable defibrillator (ICD) at the time of the MRI, without any devicerelated complications or issues with image quality
Summary
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
