Abstract

Myocardial bridging, a congenital coronary anomaly, is a cluster of myocardial fibers crossing over the epicardial coronary arteries. It is most frequently seen in the left anterior descending artery (LAD), and rarely involves the circumflex (CX) and right coronary artery (RCA). We report a patient with an unusual coronary bridge crossing over the left anterior descending, obtuse marginal and ramus intermediate branches. The patient presented with exercise-induced angina pectoris that was relieved with medical therapy.

摘要

心肌桥是一种先天性冠状动脉异常，是一束心肌纤维横跨心外膜冠状动脉。它最常见于左前降支动脉（LAD），很少累及回旋支（CX）和右冠状动脉（RCA）。我们报告一例患者，其左前降支、钝缘支和中间支上有一条不寻常的冠状动脉桥。该患者表现为运动诱发的心绞痛，经药物治疗后缓解。
