Abstract:
A child case of acute myocardial ischemia induced by symptomatic myocardial bridge (SMB)was reported and relevant literatures were reviewed in this article.The case and literatures indicate that myocardial bridge is a rare congenital coronary artery anomaly in children.The pathogenesis may be related to stenosis,spasm,arteriosclerosis of coronary artery because of myocardial bridge compression during systole.Clinical manifestations include chest pain,malignant arrhythmia,syncope,cardiac arrest and myocardial infarction.The diagnosis of myocardial bridge is based on cardiac imaging.SMB patients should be first treated with β-adrenergic; if ineffective,surgical treatment or implantable automated cardiac defibrillator shonld be chosen.The patients complicated with hypertrophic cardiomyopathy have worse conditions with high mortality.
