Abstract

Myocardial bridge is a rare congenital coronary anomaly in children, usually seen in the setting of hypertrophic cardiomyopathy and in left ventricular hypertrophy. Most myocardial bridges are believed to represent a benign anatomical variant; however, symptomatic myocardial bridge is a distinct subgroup of pathological variant, linked to myocardial ischaemia, ventricular arrhythmia, and sudden cardiac death. We present a case of a symptomatic myocardial bridge in a 5-year-old boy with mild hypertrophic cardiomyopathy who underwent supra-arterial myotomy, automatic defibrillator placement, and long-term Beta-blocker therapy. We also present 10 years of follow-up with a review of literature regarding symptomatic myocardial bridges in the paediatric age group.
