A very rare image in cardiology: posterolateral artery myocardial bridge
Tóm tắt
Muscle overlying of an epicardial coronary artery is termed a myocardial bridge. The frequency of myocardial bridging reported in angiographic studies varies from 0.5 to 16%.1 Myocardial bridging is usually confined to the left anterior descending coronary artery. A myocardial bridge of the branches of the right coronary artery is very rare.
