Myocardial bridging (MB) is a congenital coronary anomaly in which a segment of a coronary artery, most frequently the left anterior descending artery, deviates from its epicardial route by passing through the myocardium. The advent of cardiac computed tomography angiography (CCTA), equipped with its multiplane and three-dimensional functionalities, has notably enhanced the ability to identify MBs. Furthermore, novel post-processing methods have recently emerged to extract functional insights from anatomical evaluations. MB is generally considered a benign entity with very good survival rates; however, there is an increasing volume of evidence that certain MB characteristics may be associated with cardiovascular morbidity. This review is intended to depict the diagnostic and prognostic role of CCTA in the MB context.
心肌桥（MB）是一种先天性冠状动脉异常，其中一段冠状动脉，最常见的是左前降支动脉，通过心肌偏离其心外膜走行。配备多平面和三维功能的心脏计算机断层扫描血管造影（CCTA）的出现，显著提高了识别心肌桥的能力。此外，最近出现了新的后处理方法，以从解剖学评估中提取功能见解。心肌桥通常被认为是一种良性病变，生存率很高；然而，越来越多的证据表明，某些心肌桥特征可能与心血管疾病的发生有关。本综述旨在描述CCTA在心肌桥方面的诊断和预后作用。
