Note. LVEF: left ventricular ejection fraction; LVSD: left ventricular end systolic diameter; LVDD: left ventricular end diastolic diameter; LA: left atrium; RV: right ventricle; PASP: pulmonary artery systolic pressure; MR: mitral regurgitation; TR: tricuspid regurgitation. Values are in (%) or mean (SD). were present for 88–100% of parameters except RV diameter (59–63%, for total cohort, for group (1), and for group (2)) and PASP (68–77%, for total cohort, for group (1), and for group (2)); .
