In truncus arteriosus communis, as in other anomalies of conotruncal development, the coronary arterial anatomy not only differs from that found in the normal heart but also is subject to unpredictable variations. A consistently distinctive pattern was found in roughly two thirds of 31 cases, a frequency approximating that with which a distinctive coronary arterial pattern occurs in complete transposition of the great vessels. Surgical injury to a major coronary artery was identified in 2 of the 30 hearts from patients with truncus arteriosus communis who died in the early postoperative period. Of particular significance are large branches of the right coronary artery crossing the upper anterior surface of the right ventricle to supply the anterobasal surface of both ventricles and the upper part of the interventricular septum. These arteries are at special risk in surgical procedures utilizing a conduit anastomosed to a right ventriculotomy.
在共同动脉干中，如同圆锥动脉干发育的其他异常情况一样，冠状动脉解剖结构不仅与正常心脏不同，而且还存在不可预测的变异。在31例病例中，约三分之二发现了一种始终独特的模式，其频率与大动脉完全转位中出现独特冠状动脉模式的频率相近。在术后早期死亡的30例共同动脉干患者的心脏中，有2例发现主要冠状动脉受到手术损伤。特别重要的是右冠状动脉的大分支穿过右心室的上前表面，以供应两个心室的前基底部表面和室间隔的上部。在利用与右心室切开术吻合的管道的外科手术中，这些动脉处于特殊风险中。
