ICC for parameters of the right ventricle and pulmonary artery.

Variables	ICC	95%CI	P
AO (cm/m²)	0.97	0.96–0.98	＜.001
MPA (cm/m²)	0.93	0.92–0.95	＜.001
RPA (cm/m²)	0.93	0.91–0.95	＜.001
LPA (cm/m²)	0.87	0.84–0.90	＜.001
PAh (cm/m²)	0.88	0.85–0.91	＜.001
PAV (mL/m²)	0.97	0.97–0.98	＜.001
RVD/LVD	0.89	0.86–0.92	＜.001

AO = aorta, CI = confidence interval, ICC = interclass correlation coefficient, LPA = left pulmonary artery, LVD = left ventricular maximal short diameter, MPA = main pulmonary artery, PAh = pulmonary artery height, PAV = pulmonary artery volume, RPA = right pulmonary artery, RVD = right ventricular maximal short diameter, RVD/LVD = maximal short diameter of the right and left ventricles.
