Background: Untreated functional ischemic mitral regurgitation (MR) leads to reduced survival in patients undergoing coronary artery bypass grafting (CABG).However, mitral repair or replacement increases mortality and morbidity over CABG alone. The Myocor Coapsys annuloplasty system potentially reduces these risks by facilitating MR reduction on a beating heart without atriotomy. We present data from the first 11 patients completing 1-year follow-up of a total of 34 implanted patients.
Methods: Patients referred for CABG with preoperative grade 2 or greater ischemic functional MR were included in this study. Patients with structural valve defects or who demonstrated MR less than grade 2 after CABG, despite hemodynamic challenge, were intraoperatively excluded. Coapsys consists of two epicardial pads connected by a flexible chord implanted by passing the chord across the left ventricle…
