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.
