A Rare Coronary Artery Anomaly: Double Left Anterior Descending Artery

Double left anterior descending coronary artery arising from the left and right coronary arteries is one of the rarest of coronary anomalies. In this report, we present a case of double left anterior descending coronary artery with one originating from the left main stem and the second one originating from the same ostium with the right coronary artery, passing to the left side following an inter-arterial course between aorta and right ventricular outflow tract and spreading to the anterior wall of the left ventricle. The diagnosis was made with multislice computed tomography angiography. To our knowledge, only a few such cases have been published in the literature so far.
