在右心室憩室和主动脉根之间有通道的左冠状动脉主干异常，已被认为是少数人猝死的原因，其中许多人非常年轻。机械特征，如成角和压缩是最常见的原因。本文报道一名59岁男性患者，其冠状动脉异常，静息时胸痛，ST段抬高，室性心动过速，但无劳力相关心肌缺血的证据。在冠状动脉内施用硝酸甘油可以改善左主干异常冠状动脉的舒张程度。这是首例伴有室性心动过速/心室颤动的左主干冠状动脉异常并伴有异常动脉血管痉挛的病例。
An anomalous left main coronary artery with passage between the right ventricular infundibulum and aortic root has been incriminated as the causation of sudden death in a small number of individuals, many of whom are quite young. Mechanical features such as angulation and compression are most often incriminated. A 59-year-old man with such a coronary anomaly who had chest pain at rest, ST segment elevation, and ventricular tachycardia, but who had no evidence of effort-related myocardial ischemia, is reported. Improvement in the degree of coronary tone in the anomalous left main coronary with intracoronary nitroglycerin administration was demonstrated. This represents the first report of an individual with an anomalous left main coronary system with ventricular tachycardia/ventricular fibrillation and documented vasospasm in the anomalous artery.
