To the editor： Myocardial bridging （MB） is anatomically defined as a segment of a major epicardial coronary artery, which goes through the myocardium. It occurs most frequently in the midportion of the left anterior descending coronary artery. Although traditionally considered as a congenital and benign anatomic variant of the coronary artery, this condition is now associated with angina,
