Values are mean ± SD.

E/é = the ratio of early diastolic transmitral flow velocity to early diastolic mitral annular motion; LAVi = left atrial volume index; LVEDV = left ventricular end-diastolic volume; LVEF = left ventricular ejection fraction; LVESV = left ventricular end-systolic volume; LVSDV = left ventricular end-systolic volume; MAM-é = early diastolic mitral annular motion; mPAP = mean pulmonary artery pressure; Q = cardiac output; RVEDA = right ventricular end-diastolic area; RVESA = right ventricular end-systolic area; RVFAC = right ventricular fractional area change; TAM-é = early diastolic tricuspid annular motion.
