Methods of measurements of right ventricular (RV) systolic function. RV function was impaired by A tricuspid annular plane systolic excursion (TAPSE≈ 1 cm), B peak tricuspid annular systolic velocity by Pulsed-wave Tissue Doppler Imaging (S'≈ 6.5 cm) C & D RV fractional area change (FAC = 32%) calculated from RV end-diastolic area (RV EDA) and RV end-systolic area (RV ESA) and by E longitudinal RV free wall longitudinal strain (RV FWS = − 10.1%) and right ventricular global longitudinal strain (RV GLS = − 9.6%)
