Table 3 Pre-operative, 1-year and 5-year postoperative echocardiographic parameters in patients with ≥ 3 ischemic mitral regurgitation, undergoing coronary artery bypass grafting + restrictive annuloplasty (RA) vs papillary muscle approximation (PMA). Abbreviations and acronyms: IPD, interpapillary muscle distance; LVEF, left ventricular ejection fraction; MR, mitral regurgitation; LVEDD, left ventricular end diastolic diameter; LVESD, left ventricular end systolic diameter; PASP, pulmonary artery systolic pressure
From: Interpapillary muscle distance independently predicts recurrent mitral regurgitation
