A very rare congenital abnormality: double right coronary artery. A case report

Abstract

The incidence of coronary artery anomalies is about 0.6-1.3% in angiographic studies of the adult population. Double right coronary artery is one of the rarest abnormalities reported in the literature. We report a case of a double right coronary artery originating from a single orifice in a woman who underwent coronary angiography for a pathological transprosthetic aortic gradient.
