左冠状动脉异常起源于肺动脉（ALCAPA）是一种罕见的先天性异常，会导致冠状动脉系统从左向右分流，从而导致冠状动脉盗血。我们报告了一个不寻常的病例，一名健康的 48 岁患者出现劳力性呼吸困难和轻度胸痛，他接受了手术纠正这种罕见的异常情况。对于患有 ALCAPA 的成人，已经提出了多种治疗方法。尽管将左冠状动脉主干 (LMCA) 重新植入主动脉仍然是对这种异常最生理性的纠正，但 LMCA 结扎和冠状动脉旁路移植术的结合提供了双冠状动脉血流系统，并且在不可能重新植入时是优选的。
Anomalous origin of left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly that causes a left-to-right shunt via the coronary system, resulting in coronary steal. We report an unusual case of a healthy 48 years-old patient presenting with dyspnea on exertion and mild chest pain who underwent surgical correction of this rare anomaly. Multiple procedures have been proposed in adults with ALCAPA. Although re-implantation of the left main coronary artery (LMCA) to the aorta remains the most physiological correction for this anomaly, the combination of LMCA ligation and coronary artery bypass grafting provides a dual coronary flow system and is preferable when re-implantation is impossible.
