  • 6MWD: 6-min walking distance; TRV: tricuspid regurgitation velocity; RVSP: right ventricular systolic pressure; TAPSE: tricuspid annular plane systolic excursion; LVEF: left ventricular ejection fraction; PAP: pulmonary arterial pressure; PAWP: pulmonary artery wedge pressure; DPG: diastolic pressure gradient; CO: cardiac output; CI: cardiac index; PVR: pulmonary vascular resistance; RAP: right atrial pressure; SvO2: mixed venous oxygen saturation; LVEDP: left ventricular end diastolic pressure. #: right ventricular size and right ventricular systolic function were not assessable due to poor imaging quality.
