  1. PMA = papillary muscle approximation, LVP = left ventriculoplasty, LV = left ventricle, LVDd = LV end-diastolic diameter, LVEF = LV ejection fraction, LVESVI = LV end-systolic volume index, MR = mitral regurgitation, DCT = deceleration time, IPMD = interpapillary muscle distance, CH = coaptation height of the mitral valve, 2CV = 2-chamber apical view, 4CV = 4-chamber apical view.
