Table 1: Pearson correlation coefficient and Bland–Altman analysis of cross-sectional area, circumference, minimum diameter, and maximum diameter for each single plane. CSA—cross-sectional area, C—circumference, LOA—limit of agreement, RVOT—right ventricular outflow tract, BPV—basal plane of pulmonary valve, STJ—sinotubular junction, PA—pulmonary artery, BPS—bottom plane of the stent, MPS—middle plane of the stent, TPS—top plane of the stent. \(\ast\)\(p<0.001\). Figure 6: Dynamic variation in the cross-sectional area and circumference throughout the cardiac cycle at five planes from pre-operative CT. RVOT—right ventricular outflow tract, BPV—basal plane of pulmonary valve, STJ—sinotubular junction, PA—pulmonary artery. In each plane, one error bar indicates one frame (from 10% to 100%) in the cardiac cycle.
