Figure 1. Echocardiographic still images showing the calculation of right ventricular pressure dimension index. Right ventricular minor diameter is measured immediately above the tricuspid valve in end diastole (Panel A, arrows). Pulmonary artery systolic pressure was calculated using tricuspid regurgitation velocity (Panel B, arrow) and right atrial pressure estimated using inferior vena cava diameter (not shown here). Asterisk shows an implantable cardioverter-defibrillator lead within the right ventricle. LA, left atrium; LV, left ventricle; RA, right atrium; RV, right ventricle.
Figure 2. Correlations between pressure-dimension index right atrial pressure (A), right atrial to wedge pressure ratio (B) and pulmonary vascular resistance (C). Pressure-dimension index was calculated with 2-dimensional echocardiography, while all others were measured with right heart catheterization.
Figure 3. Kaplan-Meier curves for short-term survival to postoperative day 15 (A), short-term survival free of definitive right ventricular failure to postoperative day 15 (B) and long-term survival (C) for pressure-dimension index tertiles.
