Displayed parameters were measured by echocardiography except mPAP (right heart catheterization) and SV (cardiac magnetic resonance). Ea indicates arterial elastance; Ees, end-systolic elastance; ESA, end-systolic area; FAC, fractional area change; mPAP, mean pulmonary artery pressure; PAAT, pulmonary artery acceleration time; PASP, systolic pulmonary artery pressure; RV, right ventricular; SV, stroke volume; and TAPSE, tricuspid annular plane systolic excursion.
