Congenital Single Coronary Artery: A Rare Anatomic Variant

A 70 y/o male presented to the cardiac catheterization laboratory for angiography prior to valve surgery. The left main coronary artery divided into the left anterior descending (LAD) artery and circumflex (LCx). The right coronary artery (RCA) arose as an extension of the LCx, tracing the atrio-ventricular groove before terminating at the anterior base. A separate RCA ostium was absent on aortography.
