title: Multifocal coronary artery myocardial bridging involving the right coronary and left anterior descending arteries detected by ECG-gated 64 slice multidetector CT coronary angiography.
abstract: Myocardial bridging is a congenital condition in which a segment of a major epicardial coronary artery has an intramyocardial course. Myocardial bridging is usually confined to a single vessel (typically the mid segment of the left anterior descending artery) and is usually asymptomatic, however, bridging may be associated with chest pain, myocardial infarction, or sudden cardiac death. While more commonly identified at autopsy, myocardial bridging is occasionally diagnosed by coronary angiography with identification of concomitant myocardial bridging involving both the left and right coronary arteries appearing to be uncommon. We present three patients presenting with atypical chest pain symptoms in whom concomitant right coronary artery and left anterior descending artery myocardial bridging was identified by ECG gated multidetector computed tomography (MDCT).
