Abstract
Objective: To discuss the myocardial bridge (MB), with emphasis on the morphological descriptions, the clinical implications, the diagnosis and its treatment. Literature review: MB mainly affects the left anterior descending coronary artery. In the clinic, a symptomatic minority is observed, but it should be considered in patients at low risk for acute coronary disease and with symptoms of unstable or stable angina. The main clinical implications related to MB are atherosclerosis and myocardial ischemia. For diagnosis, multislice computed tomography of the coronary arteries and conventional coronary angiography are the main tests used, in which they evaluate the compression of the coronary artery by MB during systole. There is a significant discrepancy between the prevalence of in vivo examinations and the autopsy. As treatment, drug, surgical and / or percutaneous stent intervention can be performed, according to the clinical condition of each patient. Final considerations: MB remains a controversial topic, given its high asymptomatic portion, but of paramount importance for clinical and interventional cardiology in symptomatic cases.
