Why the study?
Does supra-arterial myotomy resolve myocardial ischemia and systolic narrowing in a patient with myocardial bridging?
Does supra-arterial myotomy resolve myocardial ischemia and systolic narrowing in a patient with myocardial bridging?
Supra-arterial myotomy successfully relieved symptoms and angiographic systolic narrowing in a patient with myocardial bridging at 2-year follow-up.
May support myotomy in symptomatic myocardial bridging; hypothesis-generating pending controlled trials.
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.
