Surgical Unroofing of Myocardial Bridges

Myocardial bridges (MB) are a congenital variant in which an epicardial coronary artery—
most commonly the left anterior descending (LAD)—is contained within an intramyocardial
segment. The clinical significance of this lesion varies from no symptoms to debilitating
angina, ventricular arrhythmia, and even sudden cardiac arrest Traditionally difficult to diagnose,
symptomatic myocardial bridges remain an elusive entity with a lack of clarity regarding
medical treatment and surgical indications. Importantly, studies have shown that with
appropriate patient selection, MB unroofing is an effective treatment for symptomatic
lesions, in both the adult and pediatric populations. This article describes the pre-operative
evaluation and the surgical approach for myocardial bridges.
