Figure 2.

Receiver operator curves (ROCs) representing univariate analysis of intraoperative hemodyanmic and echocardiographic measures as discriminators of severe right ventricular failure (RVF) from not-severe RVF. Odds ratios and area under the receiver operating characteristic curve (AUC) values were calculated for each of the variables of interest, along with 95% CIs. Statistical analysis was performed with SAS v9.4 (Cary, NC) with 2-sided tests and α = .05. A, ROCs for post-chest closure central venous pressure (CVP), post-chest closure pulmonary artery pulsatility index (PAPi), and RVF risk score (RVFRS). B, ROCs for post-cardiopulmonary bypass (CPB) tricuspid annular plane systolic excursion (TAPSE), post-CPB right atrial dimension major (RAdMajor), and post-CPB right ventricle fractional area of change (RVFAC).
