Anomalous aortic origins of coronary arteries (AAOCA) are congenital abnormalities involving the origin and course of coronary arteries and present with diverse clinical manifestations in patients ranging from asymptomatic incidental findings to sudden cardiac death. The current case describes a patient with an anomalous right coronary artery with an anterior interarterial course originating from a separate ostium at the left coronary cusp. By utilizing complementary multimodality imaging techniques including fractional flow reserve (FFRCT), we obtained a comprehensive functional and anatomic assessment resulting in appropriate surgical therapy and a good clinical outcome.
