Postoperative appearance after an arterial switch procedure for treatment
of dextrotransposition of the great arteries in a 21-year-old woman.
(A) Axial maximum intensity projection (MIP) CT image
shows anomalous origin of the LM from the right coronary sinus with
retroaortic course before dividing into the LAD and LCx.
(B) Axial MIP CT image shows high origin of the RCA
from the sinotubular junction with prepulmonic course before entering
into the right atrioventricular groove. Ao = aorta, LA = left atrium,
LAD = left anterior descending artery, LCx = left circumflex artery, LM
= left main trunk, MPA = main pulmonary artery, RCA = right coronary
artery.
