Anomalies of the coronary arteries originating from the right sinus of Valsalva. (1) Single coronary artery originating from the right sinus associated with fusion of the left and the non coronary cusp and atrophy of the left coronary ostium (2)Three separate coronary arteries originating from the right sinus of Valsalva

Abstract

We report three patients with the entire coronary origin arising from the right sinus of Valsalva. The first patient had a single right coronary ostium associated with a bi-leaflet aortic valve. The second patient was admitted with ST-elevation myocardial infarction (STEMI) for primary PCI. The third patient had 3 isolated ostia, all originating from the right sinus of Valsalva. Coronary anomalies are associated with increased mortality, depending on the myocardium at risk. A left main originating from the right coronary sinus is supplying a greater extent of the myocardium and is associated both with an increased incidence of symptoms and of sudden cardiac death. The possibility of such an artery anomaly should always be considered in young individuals with a history of chest pain or syncope.
