251pt RCT finds no difference between mitral repair and replacement for ischemic MR

The trial was a randomised, prospective, non-blinded, multi-institutional study of patients undergoing surgery for severe ischaemic mitral regurgitation with or without coronary revascularisation,” Dr Acker reported. A total of 251 patients were recruited, with approximately half undergoing mitral valve repair and half undergoing replacement. While there was no difference in efficacy or main safety outcomes, there was a difference in the percentage of patients experiencing a recurrence of IMR - 32.6% in the repair group versus 2.3% in the replacement group (p<0.001).
