Treatment The principle of treatment for myocardial bridges is to reduce the compression of the coronary arteries in the lower wall of the myocardial bridge, and pharmacological or surgical treatment can be used for symptomatic myocardial bridges and those with atherosclerotic plaques at the myocardial bridge. 1.Pharmacological treatment Angina caused by systolic wall coronary artery compression is effective for β-blockers, calcium antagonists (such as verapamil and diltiazem) and anti-platelet drugs. 2.Surgical treatment Surgical treatment should be performed if the angina is difficult to control by medication. There are two types of surgery, namely myocardial bridge resection and coronary artery bypass grafting. (1) Myocardial bridge resection is suitable for superficial type, and the myocardial bridge is found under general anesthesia at room temperature to completely remove the compression on the coronary artery and restore the distal blood flow. Simple myocardial bridge resection is rarely performed in conjunction with coronary artery bypass grafting. (2) Coronary artery bypass grafting is indicated for those with longitudinal or combined atherosclerotic stenosis. Coronary artery bypass grafting can be performed under normothermic general anesthesia, normothermic extracorporeal circulation or hypothermic extracorporeal circulation. The graft material can be autologous saphenous vein or internal mammary artery.
