The significance of coronary artery muscle bridging (MB) has been debated since its first angiographic description by Portsmann and colleagues in 1960 (1). The course is usually benign; however, angina, myocardial infarction, sudden death, arrhythmias, and complete heart block have been reported. In this article, we present a case of coronary artery muscle bridging which caused a patient with no angiographic evidence of atherosclerosis to experience Class III angina.
自1960年波特斯曼及其同事首次通过血管造影描述冠状动脉肌桥（MB）以来，其意义一直存在争议（1）。其病程通常为良性；然而，也有报道称出现了心绞痛、心肌梗死、猝死、心律失常和完全性心脏传导阻滞。在本文中，我们报告了一例冠状动脉肌桥病例，该病例导致一名无动脉粥样硬化血管造影证据的患者出现Ⅲ级心绞痛。
