Myocardial bridging (MB) is a congenital coronary anomaly in which a segment of the epicardial coronary artery traverses through the myocardium for a portion of its length. The muscle overlying the artery is termed a myocardial bridge, and the intramyocardial segment is referred to as a tunneled artery. MB can occur in any coronary artery, although is most commonly seen in the left anterior descending artery. Although traditionally considered benign in nature, increasing attention is being given to specific subsets of MB associated with ischemic symptomatology. The advent of contemporary functional and anatomic imaging modalities, both invasive and noninvasive, have dramatically improved our understanding of dynamic pathophysiology associated with MBs. This review provides a contemporary overview of epidemiology, pathobiology, diagnosis, functional assessment, and management of MBs.

心肌桥接：诊断、功能评估和管理：JACC 最新综述

心肌桥接（MB）是一种先天性冠状动脉异常，其中心外膜冠状动脉的一部分穿过心肌，其长度的一部分。覆盖在动脉上的肌肉称为心肌桥，心肌内段称为隧道动脉。MB 可发生在任何冠状动脉，但最常见于左前降支。虽然传统上认为本质上是良性的，但人们越来越关注与缺血症状相关的 MB 的特定亚群。当代功能性和解剖成像方式（包括侵入性和非侵入性）的出现极大地提高了我们对与 MB 相关的动态病理生理学的理解。本综述对 MB 的流行病学、病理生物学、诊断、功能评估和管理进行了当代概述。
