Mitral regurgitation at the time of left ventricular assist device implantation: Should it be treated or not?

Significant mitral regurgitation may be prevented by concomitant surgery, but late survival and the risk of other major adverse events were not significantly improved by the procedure and were similar between patients with untreated moderate or greater mitral regurgitation and those with no or untreated mild mitral regurgitation. Our results suggest that mitral regurgitation during left ventricular assist device implantation may have only limited benefits from concomitant surgery.
