  1. Initiation represents the first hospitalization of this patient in our hospital because of progressive dyspnea. LVEDD: end-diastolic left ventricular dimension; IVSd: end-diastolic interventricular septal thickness; LAD: end-systolic left atrial diameter; RVD: end-diastolic basal right ventricular dimension; RVd: end-diastolic right ventricular free wall thickness; RAA: end-systolic right atrial area; LV: left ventricle; EF: ejection fraction; RV: right ventricle; FAC: fractional area change; MAPSE: mitral annular plane systolic excursion; TAPSE: tricuspid annular plane systolic excursion; TR: tricuspid regurgitation; maxV: maximal velocity; maxPG: maximal pressure gradient; RVOT: right ventricular outflow tract; VTI: velocity-time integral; PVR: pulmonary vascular resistance, estimated PVR by echocardiography formula: 10 × (TR maxV/VTIRVOT) − 0.16; CI: cardiac output indexed to body surface area; Woods units: mmHgmin/L; RAP: estimated right atrial pressure; PA: pulmonary artery; RA: right atrium; 6MWD: 6-min walk distance test.
