The coronary artery anatomy in patients with transposition of the great artery (TGA) is a contributing factor for outcome in arterial switch procedure. A full-term, 7-day-old baby boy diagnosed as dextro-TGA (dTGA) with intact ventricular septum. Intraoperatively, the left coronary sinus had a blind indentation from which a firm cord-like left main coronary artery originates. Procedure completed as usual for a routine arterial switch operation. About 5% of patients with D-TGA have a single coronary artery. Assessment of blood flow to all branches intraoperatively is mandatory to choose between either transfer of single ostium or bypass grafting to the other coronary system.
大动脉转位（TGA）患者的冠状动脉解剖结构是动脉调转手术预后的一个影响因素。一名足月、7天大的男婴被诊断为右型大动脉转位（dTGA），室间隔完整。术中，左冠状窦有一个盲端凹陷，一条坚韧的索状左主冠状动脉由此发出。手术按常规动脉调转手术照常完成。约5%的右型大动脉转位患者有单一冠状动脉。术中必须评估所有分支的血流情况，以便在单开口移植或搭桥至另一冠状动脉系统之间做出选择。
