Anomalous origin of the left coronary artery (ALCA) arising from the pulmonary artery is a rare anomary, and causes myocardial infarction and death in children. Direct implantation of ALCA to the aorta was performed in the 6-year-old female patient. A large button of pulmonary arterial wall resected with ALCA could spare the shortage of the distance between the aorta and the ALCA. Postoperative catheterization displayed non-stenotic left coronary artery. Left ventricular function assessed by echocardiography showed improvement. Cold area in early stage postoperative myocardial imaging disappeared one year after the surgery, which suggested the hibernation of the preoperative myocardium.
左冠状动脉异常起源于肺动脉是一种罕见的异常情况，可导致儿童心肌梗死和死亡。对一名6岁女性患者进行了左冠状动脉直接植入主动脉的手术。与左冠状动脉一起切除的一大块肺动脉壁纽扣状组织可弥补主动脉与左冠状动脉之间距离的不足。术后导管检查显示左冠状动脉无狭窄。通过超声心动图评估的左心室功能有所改善。术后早期心肌成像中的冷区在手术后一年消失，这提示术前心肌存在冬眠现象。
