Ischemic mitral regurgitation (IMR) recurrence after combined coronary artery bypass grafting (CABG) and mitral valve repair does occur, with a prevalence of 20% to 30% at the 2- to 4-year follow-up. This single-center study aims to identify the predictors of IMR improvement after surgical revascularization plus mitral valve repair for moderate IMR. ⋯ An LVEDD of less than 65 mm, the use of a rigid complete ring, and combined restrictive annuloplasty and subvalvular and/or leaflet repair are associated with IMR improvement after CABG plus mitral valve repair for the treatment of moderate IMR; IMR improvement 2 years after surgery is associated with improved midterm outcomes.
