Key: TAPSE Tricuspid annular plane systolic excursion, LV left ventricle, E:A transvalvular filling velocities ratio, E/e’ ratio of early filling to averaged early diastolic tissue Doppler velocities of mitral or tricuspid valves, PAP pulmonary artery pressure, RIMP right ventricular (RV) index of myocardial performance. Results are presented as means ± standard deviations, or as numbers with percentages in parentheses. *p-vlaue is statistically significant
