Repair of ischemic mitral regurgitation: comparison between flexible and rigid annuloplasty rings.

Background: The surgical treatment of ischemic mitral regurgitation (MR) usually involves implantation of an annuloplasty ring. We compared results of mitral valve repair using a flexible or a rigid annuloplasty ring in patients with ischemic MR undergoing coronary artery bypass graft surgery.

Methods: There were 169 patients.
