Arterial Switch Operation for Transposition of the Great Arteries With Coronary Arteries From a Single Aortic Sinus

All single sinus coronary artery with single ostium can be transferred with the trap-door technique with excellent results. The aortocoronary flap technique in those with separate ostia with or without intramural left coronary artery may be a good option. However, reimplantation of the intramural left coronary artery using separate coronary buttons should be performed with great care.
