title: Right coronary artery arising as a sidebranch from the left anterior descending artery: a single coronary ostium anomaly.
abstract: We present a patient with abnormal origin of the right coronary artery from the left anterior descending artery. The patient had chest pain probably related to myocardial ischemia. This anomaly is very rare and has only been reported in a few cases. The abnormal vessel had a rightward course following its take-off from the left anterior descending artery and remained anterior to the main pulmonary artery. There was no significant obstruction. The mechanism of myocardial ischemia remains unexplained.
