title: A rare coronary artery anomaly: anomalous right coronary artery arising from the left anterior descending artery.
abstract: Anomalous right coronary artery is a rare entity with an incidence of 0.26%. The anomalous origin usually arises from the left sinus valsalva. An anomalous right coronary artery arising from the left anterior descending artery is rare. It is usually known as a benign entity but may have clinical importance due to its course between the aorta and pulmonary artery which may cause myocardial ischemia or sudden cardiac death. Here we present an anomalous coronary artery arising from the left anterior descending artery detected by coronary artery angiogram and confirmed by multislice computed tomography thereafter. 40% retrospective electrocardiographic gating is performed and volume-rendered 3 D and axial MIP (maximum intensity projection) images were reconstructed on a Vitrea post- processing Workstation. The images demonstrated the anomalous origin of the right coronary artery arising from the proximal portion of left anterior descending artery after the first septal perforator and coursing.
