A Rare Case of Double Myocardial Bridges ofthe Left Anterior Descending Artery

Myocardial bridge is a benign congenital anomaly in which a segment of major epicardial coronary arteries descends into the myocardium for a variable distance. Myocardial bridge is most often single and located in the middle part of the left anterior descending artery. The presence of more than one myocardial bridge in coronaryarteries is very rare. We present a patient with more than one myocardial bridge in the left anterior descendingartery. The case was a 55- year old man, referred to our clinic with the complaint of atypical chest pain. In the radionucloid study a reversible ischemia in the anterior wall was found. For this abnormal finding. he underwent a coronary angiography and it showed two myocardial bridges in the mid and end segments of the left anteriordescending artery. Since myocardial bridge is usually single, the present case with two consecutive myocardial bridges in one arterycan be presented as a very rare case report.
