PURPOSE: Various devices have been developed for the transcatheter closure of secundum @entity118 ( @entity30160 ) to avoid the morbidity, discomfort, and thoracotomy scar associated with surgical closure. The purpose of this study was to evaluate the safety and efficacy of the Amplatzer septal occluder for transcatheter closure of @entity30160 . @entity1 AND METHODS: Only @entity1 who were clinically diagnosed with @entity30160 were selected. The anatomy of @entity2438 had to meet certain echocardiographic criteria. Under the guidance of echocardiography and fluoroscopy, the implantation of the device was accomplished as recommended by the manufacturer. RESULTS: Thirty @entity1 (median age 18.4 years) with an @entity30160 underwent transcatheter closure. Procedure time ranged from 30-200 minutes and fluoroscopy time from 10-50 minutes. The diameter of the @entity2438 measured by echocardiography ranged from 13-25 mm, while both the stretched diameters of the ASDs and the sizes of the devices ranged from 18-34 mm. The successful placement rate was 100%. The residual shunt rate was 100% immediately after device implantation and 10% after 24 hours. After 3 months, 3.3% of the @entity1 had a (trivial) residual shunt. The device did not affect the surrounding structures of @entity2438 . No embolization of the device occurred. CONCLUSION: The Amplatzer device designed for the closure of @entity30160 can be implanted easily and also is retrievable. Due to a low ratio of residual shunt and few complications, this device is a good choice for transcatheter closure of @entity30160 . Long-term follow-up will be required for widespread clinical use.
