Key result
Retransposition of the pulmonary artery, coronary arteries, and aorta at the arterial level was successfully performed in a 20-month-old child with classic transposition of the great arteries.
Case Report (n=1)
This early case report demonstrates the technical feasibility of the arterial switch operation for transposition of the great arteries, while highlighting technical challenges with coronary reimplantation.
Feasibility of arterial switch beyond infancy shown in one case; leaves open safety, durability, and generalizability pending prospective data.
In a 20-month-old child with classic transposition of the great arteries the pulmonary artery, coronary arteries, and aorta were successfully retransposed at arterial level. It was difficult to reimplant the coronary arteries in the dilated pulmonary artery root without damaging the attachments of the valve cusps, and it may be better to divide the pulmonary artery first to avoid this hazard. Retransposition at arterial level will not be suitable for all patients with transposition of the great arteries, and many questions about long-term outcome remain to be answered.

Ross et al. (1976) conducted a case report in Classic transposition of the great arteries (n=1). Retransposition at arterial level was evaluated on Successful retransposition. Retransposition of the pulmonary artery, coronary arteries, and aorta at the arterial level was successfully performed in a 20-month-old child with classic transposition of the great arteries.
