Myocardial Bridging: Review on the Role of Coronary Computed Tomography Angiography

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.

Automated summary

Myocardial bridging is a congenital coronary anomaly where a segment of a coronary artery deviates from its normal route and passes through the myocardium. The use of cardiac computed tomography angiography has greatly improved the ability to identify myocardial bridging. Furthermore, new post-processing methods have emerged to extract functional insights from anatomical evaluations. Although myocardial bridging is generally considered benign, there is increasing evidence that certain characteristics may be associated with cardiovascular morbidity.
