Surgical Treatment of Moderate Ischemic Mitral Regurgitation [1]
301 pts with CAD required revascularization and moderate MR were randomly assigned to CABG or CABG with MV repair. The outcome was LV end-systolic index at 1 year. MV repair contributed to longer pump times, longer hospitalization, and more neurologic events. MV repair did not result in an improved primary outcome at 1 year, but was associated with reduced rates of moderate to severe MR. The potential benefit of this latter finding is unclear.
