Anomalous origin of the left main coronary artery from the right sinus of Valsalva is extremely rare and can lead to sudden cardiac death. We report a case in which an 18-year-old college student collapsed immediately after a long-distance run of 10 km. After cardiopulmonary resuscitation and electrical shock for ventricular fibrillation, she experienced a return of spontaneous circulation. Cardiac catheterization and cardiac computed tomographic angiography revealed an unusually long intramural course of the left main coronary artery from the right sinus of Valsalva. The young woman underwent a successful unroofing operation for coronary artery correction. She remained asymptomatic upon exercise during 2.5 years of follow-up.
左主冠状动脉起源于瓦尔萨尔瓦窦右侧极为罕见,可导致心源性猝死。我们报告一例18岁大学生在10公里长跑后即刻倒地的病例。在进行心肺复苏和除颤治疗心室颤动后,她恢复了自主循环。心脏导管检查和心脏计算机断层血管造影显示左主冠状动脉自瓦尔萨尔瓦窦右侧发出后有一段异常长的壁内走行。该年轻女性接受了成功的冠状动脉矫正开窗手术。在2.5年的随访中,她运动时无症状。
