Abstract
- Myocardial bridge is not a rare congenital malformation of the coronary artery which takes an intramural course. Most of the lesions are found in proximal half of the left anterior descending coronary artery, but one which occurs in the left circumflex artery is extremely rare. During systole, the intramural coronary artery is compressed by contraction of over bridging ventricular muscle, therefore blood flow distal to the lesion in impaired and angina pectoris or acute myocardial infarction may occur. We experienced a 54-year-old man who complained of severe precordial pain during exercise and at rest for several months, and was diagnosed as myocardial bridging in the left circumflex coronary artery by coronary arteriography. Thus we report this case with literature review.
