A rare unclassified coronary anomaly: Right coronary artery with dual ostia origin from the right aortic sinus of Valsalva

Abstract

The dual ostia of coronary artery is extremely rare entity. We present a case of old woman with right coronary artery with dual ostia origin from the right aortic sinus of Valsalva. A 52-year-old woman presented with discontinuous chest tightness and palpitation. she was referred to coronary computed tomography angiography (CCTA). The CCTA suggested an anomalous right coronary artery (RCA) origin from the right sinus of Valsalva (RSV) with dual ostia. The dual ostia of coronary anomaly is extremely rare entity. Though catheter angiography may be performed for preoperative identification of coronary anomalies, it is limited in the description of the relationship of the coronary arteries to the cardiac structures and great vessels. CCTA can help in noninvasive characterization of coronary anomalies with respect to their origin, course, and spatial relations. Interventional cardiologists and cardiac surgeons should be aware of the new coronary anomaly for appropriate procedural planning and intra-procedural management. The important imaging valueof CCTA can help in noninvasive characterization of coronary anomalies with respect to their origin, course, and spatial relations.
