Myocardial bridging: surgical technique and operative results.

We report a case of a 37-year-old symptomatic male with anterior myocardial ischemia. Coronary angiography demonstrated systolic obstruction of the midportion of the left anterior descending coronary artery due to myocardial bridging. The patient was treated with a supra-arterial myotomy. Two years postoperatively, the patient is without evidence of myocardial ischemia. Angiography, 2 years postoperatively, shows no evidence of systolic narrowing of the left anterior descending coronary artery.
