Anomalous aortic origin of coronary arteries is a @entity4297 in which one coronary artery arises from the opposite sinus (the left coronary artery from the right coronary sinus, or the right coronary artery from the left sinus). The initial segment of the abnormal artery courses between the great arteries and is usually located within the aortic wall. These anomalies are far from rare, affecting 0.1% to 0.3% of the population, and carry a high risk of @entity1164 . It is thought that the main mechanism of @entity204 is external compression of the abnormal coronary artery between the great arteries as they expand during strenuous exercise. The risk of @entity944 is particularly high in @entity1 with an @entity453 or associated anatomic lesions (stenotic intramural segment, slit-like deformation of the ostium), and also in young athletes. A common presentation is sudden unexplained @entity204 . The diagnosis can be made by echocardiographic examination. Silent @entity741 must be sought, with stress echocardiography and stress nuclear imaging. Various surgical techniques have been described. Our own technique involves the creation of a neo-ostium in the appropriate sinus. Surgical treatment is relatively safe and provides satisfactory results, most @entity1 having no residual @entity741 under stress. Surgery is recommended for all @entity1 with an @entity453 , regardless of symptom status, as well as for symptomatic @entity1 with an anomalous right coronary artery (aborted @entity944 , symptoms under stress, @entity741 under stress). Because of the incidence and severity of these anomalies, careful echocardiographic evaluation should be performed routinely, at least in young athletes.
