Table 2 Operative variables of 96 patients undergoing surgical repair for ischemic mitral valve regurgitation.All patients received coronary artery bypass grafting (CABG) and reduction annuloplasty (RA).After 1:1 randomization, 48 patients also received papillary muscle approximation (PMA).ACX = aortic cross clamp time; CPB = cardiopulmonary bypass time
From: Interpapillary muscle distance independently predicts recurrent mitral regurgitation
