Representative echocardiographic images of RVEDTD, PASP, PAd, and tricuspid annular plane systolic excursion as well as the score calculation for two patients. Column A (top to bottom) shows ↑RVEDTD and ↑PASP (score =−1). Invasive hemodynamics: mPAP =30 mmHg, PAWP =11 mmHg, PVR =6.0 Wood units, and cardiac index =3.1 L/min/m². Column B shows ↑RVEDTD, ↑PASP, ↑PAd, and ↓TAPSE (score =4). Invasive hemodynamics: mPAP =39 mmHg, PAWP =11 mmHg, PVR =6.0 Wood units, and cardiac index =3.35 L/min/m².

Abbreviations: RVEDTD, right ventricular end-diastolic transverse dimension; PASP, pulmonary arterial systolic pressure; PAd, pulmonary artery diameter; mPAP, mean pulmonary artery pressure; PAWP, pulmonary artery wedge pressure; PVR, pulmonary vascular resistance; TAPSE, tricuspid annular plane systolic excursion; ESI, echocardiography scoring index.
