Impaired local pulmonary arterial size and increased right ventricular pressure after hybrid procedure and staged biventricular repair. Z-score of left (A) and right (B) pulmonary artery before and after cardiac repair. C Nakata index and D lower lobe index normalized to body surface area after biventricular repair. E Right ventricular systolic pressure after biventricular repair. F Left ventricular enddiastolic pressure after biventricular repair. PA pulmonary artery, *p < 0.05
