Anomalous origin of the left anterior descending coronary artery with associated congenital defects is very rare. An angiogram of a 47-year-old woman admitted for a ventricular septal defect closure revealed an anomalous left anterior descending coronary artery arising from the left posterior sinus of the pulmonary artery. During the surgical procedure, the origin of the left anterior descending coronary artery was closed with pledgetted polypropylene sutures through the pulmonary artery. The ventricular septal defect was closed with a patch through the right atrium, and the left anterior descending coronary artery was bypassed with the left internal mammary artery.
左前降支冠状动脉异常起源并伴有相关先天性缺陷的情况极为罕见。一名因室间隔缺损修补入院的47岁女性的血管造影显示，左前降支冠状动脉起源于肺动脉左后窦。在手术过程中，通过肺动脉用带垫片的聚丙烯缝线封闭左前降支冠状动脉的起源。通过右心房用补片封闭室间隔缺损，并用左乳内动脉对左前降支冠状动脉进行搭桥。
