Moderate ischemic mitral regurgitation and coronary artery bypass surgery: effect of mitral repair on clinical outcome.

Background And Aim Of The Study: The optimal management of moderate (grade 2-3+) ischemic mitral regurgitation (MR) at the time of coronary artery bypass grafting (CABG) remains the subject of controversy. The study aim was to determine whether mitral repair associated with CABG is preferable to CABG alone in patients with moderate ischemic MR, in terms of intermediate outcome.

Methods: Among 60 patients with moderate ischemic MR, 30 who underwent CABG plus mitral repair were compared with 30 others who underwent CABG alone.
