Three-dimensional reconstruction rendered from the electrocardiogram-gated contrast computed tomography of the heart in the arterial phase, demonstrating the anatomical condition in the patient with congenitally corrected transposition of the great arteries and dextrocardia. (A) The anterior position rotated by 28° up and by 23° to the left. (B) The posterior position rotated by 67° down and by 130° to the right. AO, aorta; CS, coronary sinus; LV, left ventricle; PA, pulmonary artery; RV, right ventricle; white solid arrow, ventricular electrode; white dashed arrow, atrial electrode.
