BACKGROUND: @entity2461 ( @entity2461 ) is one of the most common congenital @entity299 and began to get treated by transcatheter occlusion since 1997 in China. Since then, several devices have been invented for occluding @entity2461 . This study aimed to evaluate the technical feasibility, safety, and efficacy of transcatheter occlusion of @entity2461 with different devices. METHODS: One thousand five hundred and twenty-six @entity1 (537 @entity1 , 989 @entity1 ) with @entity2461 from January 1997 to September 2014 underwent descending aortogram and transcatheter occlusion procedure. We retrospectively analyzed data of these @entity1 , including gender, age, weight, size and morphology of @entity2461 , and devices used in transcatheter occlusion, outcomes, and postoperational complications. RESULTS: Median age and median weight were 4.0 years (range: 0.3-52.0 years old) and 15.3 kg (range: 4.5-91.0 kg), respectively. Mean ductal diameter, aortic ductal diameter, ductal length, and pulmonary artery pressure were 3.50    2.15 mm, 10.08    2.46 mm, 7.49    3.02 mm, and 30.21    17.28 mmHg, respectively. Morphology of @entity2461 assessed by descending aortogram was of type A in 1428 @entity1 , type B in 6 @entity1 , type C in 79 @entity1 , type D in 4 @entity1 , and type E in 9 @entity1 according to the classification of Krichenko. Of all the 1526 @entity1 , 1497 @entity1 underwent transcatheter @entity2461 closure, among which 1492 were successful. Devices used were Amplatzer duct occluder I (ADO I, 1280, 85.8%), Cook detachable coils (116, 7.8%), ADO II (ADO II, 68, 4.6%), muscular @entity1757 occluder (12, 0.8%), and Amplatzer vascular plug (16, 1.0%). CONCLUSIONS: Excellent occlusion rates with low complication rates were achieved with all devices regardless of @entity2461 types. With transcatheter occlusion technique and devices developing, more @entity1 with @entity2461 can be treated with transcatheter closure both safely and efficiently.
