Key result
Surgical myotomy is preferred for symptomatic myocardial bridging refractory to beta-blockers.
Why the study?
Myocardial bridging is rare and presents with variable anatomic features and clinical manifestations, with limited data on optimal treatment strategies.
Myocardial bridging is a rare condition that can cause ischemia or arrhythmias, typically managed with beta-blockers or myotomy for refractory cases, while stenting has limited use.

Myocardial bridging evaluation may be considered in refractory angina; leaves open optimal intervention thresholds and outcomes in nonresponders.
Myocardial bridging is rare. Myocardial bridges are most commonly localized in the middle segment of the left anterior descending coronary artery. The anatomic features of the bridges vary significantly. Alterations of the endothelial morphology and the vasoactive agents impact on the progression of atherosclerosis of myocardial bridging. Patients may present with chest pain, myocardial infarction, arrhythmia and even sudden death. Patients who respond poorly to the medical treatment with β-blockers warrant a surgical intervention. Myotomy is a preferred surgical procedure for the symptomatic patients. Coronary stent deployment has been in limited use due to the unsatisfactory long-term results.

Shi‐Min Yuan (2015) conducted a review in Myocardial bridging. Myocardial bridging is a rare condition that can cause myocardial infarction or sudden death, with surgical myotomy being the preferred treatment for patients unresponsive to beta-blockers.
