Anomalous origin of the left coronary artery from the main pulmonary trunk results in myocardial ischemia or infarction, and may be a cause of death in the first months of life. Some patients, however, develop satisfactory coronary collateral circulation and remain asymptomatic into adulthood. In these patients, myocardial perfusion and left ventricular function are not well understood. We report the case of a 17-yr-old female patient, suffering from anomalous origin of the left coronary artery from the main pulmonary trunk, who underwent reimplantation of the left coronary artery to the aorta. The preoperative permanent 201Tl defect of the left antero-lateral ventricular wall and the abnormal regional wall motion induced by stress exercise testing were fully reversed after the operation.
左冠状动脉起源于主肺动脉干异常可导致心肌缺血或梗死，可能是生命最初几个月内的死亡原因。然而，一些患者会形成令人满意的冠状动脉侧支循环，并在成年后仍无症状。在这些患者中，心肌灌注和左心室功能尚不清楚。我们报告了一例17岁女性患者，其左冠状动脉起源于主肺动脉干异常，接受了左冠状动脉重新植入主动脉手术。术后，术前左前外侧心室壁永久性铊-201缺损以及应激运动试验诱发的异常节段性室壁运动完全恢复正常。
