Data are presented as n or mean±sd, unless otherwise stated. RVEDVI: right ventricular (RV) end-diastolic volume index; RVESVI: RV end-systolic volume index; RVSVI: RV stroke volume index; RVEF: RV ejection fraction; VMI: ventricular mass index; LVEDVI: left ventricular (LV) end-diastolic volume index; LVESVI: LV end-systolic volume index; LVSVI: LV stroke volume index; LVEF: LV ejection fraction. #: defined as RV mass divided by LV mass; ¶: ratio of RV diameter to biventricular diameter in early diastolic phase of the ventricle.
