0445: Isolated anomalous connections of the coronary arteries: an observational cohort of more than 450 young people or adults (ANOCOR study)

Isolated proximal anomalous connections of the coronary arteries (ANOCOR) are rare and sometimes raise diagnostic and therapeutic problems. The prognosis depends mainly on the initial course of the ectopic vessel. In the current guidelines, surgical repair is recommanded for high risk ANOCOR. The lack of controlled studies and scarcity of data concerning the long-term evaluation of ANOCOR corrected or not may explain the discordance noticed between recommandations and practices. Large-scale prospective multicenter registries dedicated to ANOCOR are needed to achieve a better understanding of the clinical profile and the impact of correction on the natural history of these congenital coronary abnormalities. The ANOCOR study began 31st January, 2010 with an inclusion period of 3 years. More than 450 young people (≥15-year-old) and adults have been included by 71 interventional cardiologists from the Interventional Working Group (GACI) of the French Society of Cardiology. A 5-years follow-up was scheduled. Clinical characteristics, angiographic patterns and computed tomography images, as well as the initial management of the ANOCOR cohort patients will be presented.
