This study was approved by the institutional review board (2023-0965) with waiver of individual consent. A male baby weighing 3.32 kg, who had been prenatally diagnosed with congenitally corrected transposition of the great arteries and right atrial isomerism (RAI), was born at 39 weeks and 2 days of gestation. Postnatal cardiac computed tomography (CCT) scan revealed bilateral superior venae cavae (SVCs) draining directly to each atria, total anomalous pulmonary venous drainage (TAPVD) draining into the left SVC, the inferior vena cava draining to the left-sided atrium, the separate right hepatic vein draining to the right-sided atrium (RA), large atrial septal defect, ventricular d-looping with morphologic right ventricle in the right and morphologic left ventricle in the left, intact ventricular septum, ventriculoarterial discordance, and usual coronary artery pattern (ie, 1LC x 2R) (Figure 1).
