Myocardial bridge is a congenital anatomical variant, most patients have no clinical symptoms, but individual patients may present with angina pectoris, myocardial infarction or even sudden death. In recent years, with the common development of coronary CT and coronary angiography, the trend of myocardial bridge detection is on the rise. Under normal circumstances, coronary arteries and their branches mainly travel in subepicardial fatty tissue or deep surface of epicardium, sometimes they are partially covered by myocardium, and the blood flow of coronary arteries is affected by the myocardial fibers covering its surface to varying degrees. This part of the coronary artery is called the wall coronary artery, and this part of the myocardial fibers is called myocardial bridge. This part of the coronary artery is called the wall coronary artery, and this part of the myocardial fibers is called the myocardial bridge. The rate of coronary angiographic findings is inconsistent, ranging from 0.5% to 16%, and varies widely, probably because most patients do not have significant clinical symptoms and must have a more significant systolic stenosis to be seen on angiography. The clinical presentation of patients with myocardial bridges varies widely, with most having no obvious symptoms. As a result, some patients may present with angina pectoris, arrhythmia, or even sudden death due to myocardial infarction. Patients with myocardial bridges do not need special treatment if they are asymptomatic or have mild symptoms. For patients with class II-III myocardial bridges and obvious symptoms, they can be treated with medication, interventional therapy or surgical procedures.
