Coronary Ostial Dimple (In the Posterior Aortic Sinus) in the Absence of Other Coronary Arterial Abnormalities
Document Type
Article
Abstract
Normally 2 coronary arteries arise from the aorta, 1 from the aortic wall enclosing the right aortic sinus and the other from the aortic wall enclosing the left aortic sinus; the wall enclosing the posterior, i.e., noncoronary sinus, is smooth and devoid of any “dimples” or “buds” or other suggestions of a residua of a potential coronary ostium. Coronary artery ostia arise from the wall of the aortopulmonary trunk at the time of embryonic division of the trunk. This epicardial vascular network, then, induces the formation of the coronary ostial dimples as it approaches the aortopulmonary trunk. In addition to the heretofore described patient, at least 6 other cases of coronary ostial dimples or buds have been reported. The right and left coronary ostia are located in the wall of the aorta slightly below and at this sinotubular junction, respectively. The coronary ostial dimple is located slightly above the sinotubular junction.
