A comparison of the LV and RV characteristics. (A) A value of TAPSE was higher in patients with LVEF of ≥ 40%. (B) A value of RV sphericity index was higher in patients with PH. LV, left ventricular; LVEF, left ventricular ejection fraction; PH, pulmonary hypertension; RV, right ventricular; TAPSE, tricuspid annular plane systolic excursion.
