Clinical impact of TAPSE and RV sphericity index on 2-year MACCE. The patients were classified into group 1 (TAPSE of ≥ 19 mm and RV sphericity index of < 0.377), group 2 (TAPSE of < 19 mm and RV sphericity of < 0.377), group 3 (TAPSE of ≥ 19 mm and RV sphericity index of ≥ 0.377), and group 4 (TAPSE of < 19 mm and RV sphericity index of < 0.377). Kaplan–Meier survival curve demonstrated that the incidence of MACCE at 2 years differed among the above groups (p = 0.002). Patients with abnormal values of TAPSE and RV sphericity index (group 4) indicated the highest incidence of the outcomes. MACCE, major adverse cardiac and cerebrovascular events; RV, right ventricular; TAPSE, tricuspid annular plane systolic excursion.
