RESUMO
Myocardial bridges (MB) are rarely observed but well known pathology of the major epicardial coronary arteries which are embedded in the overlying myocardial tissue. It is most frequently found in young patients with hypertrophic cardiomyopathy (HCM). Myocardial bridges are associated with myocardial ischemia and infarction, cardiac arrhythmias and sudden death. The present case series report the outcomes of three symptomatic patients with hypertrophic cardiomyopathy who underwent myocardial muscle debridges. They were operated using beating heart technique without cardiopulmonary bypass. The authors conclude that off-pump supracoronary muscle myotomy is a feasible treatment modality in the young age group with non-obstructive hypertrophic cardiomyopathy.
