Abstract:
A patient with dual left anterior descending (R. interventricularis anterior of the left coronary artery) coronary artery is presented. A normally arising left anterior descending was hypoplastic, and an anomalous left anterior descending, which arose from the right sinus aorticus had a normal caliber. The anomalous left anterior descending artery traversed between the aorta and the pulmonary artery supplying most of the anterior myocardial wall of the left ventricle. This rare coronary anomaly can potentially have implications on percutaneous coronary interventions or on surgical revascularization procedures.
