Extensive Myocardial Bridging Treated with CABG

Abstract

Myocardial bridging is generally considered a benign condition, however with significant systolic compression can cause ischemia, spasm, or malignant arrhythmias. Generally, myocardial bridging occurs in the left anterior descending artery in approximately 80% of cases. First-line therapy includes beta-blockers and calcium channel blockers but refractory cases usually requires surgical intervention with myotomy or coronary artery bypass grafting. The decision to undergo surgical management of myocardial bridging is difficult as many of these patients are young and otherwise healthy therefore long-term outcomes of surgical intervention should be considered carefully prior to pursuing surgical management. We present a case of refractory anginal symptoms relieved with coronary artery bypass grafting.
