Abstract

The importance of myocardial bridging of a coronary artery in the setting of hypertrophic cardiomyopathy is controversial, although we have previously reported an association with myocardial ischemia and sudden death in children. We report five symptomatic children in whom symptoms or evidence of myocardial ischemia resolved or improved after supraarterial myotomy alone.
