Resolution of Mitral Regurgitation With Left Ventricular Assist Device Support

LVAD implantation unloads the left ventricle to promote left ventricle reverse remodeling and correct functional MR across all severity levels. The resolution of MR is sustained at 180 days post-LVAD. These results coupled with no survival difference with uncorrected MR between < moderate-severe MR and ≥ moderate-severe MR makes concomitant mitral valve repair or replacement at the time of LVAD implantation unnecessary.
