Boxplots are shown by shunt type at all four intervals for neo-aortic cardiac index (panel A; pre-Norwood N=327, post-Norwood N=397, pre-stage II N=330, 14 months N=286), neo-aortic ejection time (panel B; pre-Norwood N=363, post-Norwood N=419, pre-stage II N=353, 14 months N=303), and neo-aortic peak distal arch velocity (panel C; post-Norwood N=355, pre-stage II N=298, 14 months N=264). All 3 neo-aortic flow indices are significantly different (P<0.001) at post-Norwood and pre-stage II with decreased cardiac index, ejection time and peak distal arch velocity in the RVPAS compared to MBTS, but these indices were not significantly different at baseline and 14 months.
