Transcatheter Closure of Patent Ductus Arteriosus Using Ado Device: Retrospective Study of 149 Patients

BACKGROUND: Patent ductus arteriosus (PDA) is a common form of congenital heart disease and forms about 5-10% of congenital heart diseases. Surgical closure is safe and effective; however, certain patients may experience some morbidity. Recently, transcatheter closure of PDA using the Amplatzer duct occluder has been shown to be safe and efficacious. OBJECTIVES: To evaluate whether transcatheter closure with this device offers an alternative to surgical closure of PDA. PATIENTS AND METHODS: Between July 2006 to July 2008, 149 patients (98 females and 51 males) with PDA underwent cardiac catheterization in an attempt to close their PDA by transcatheter approach using Amplatzer duct occluder device. RESULTS: The patient's age ranged from 4 months to 45 years (median 5 years). Successful PDA closure was achieved in 136 patients (91.2%) with 100% complete closure rate within 24 hours after the procedure. Thirteen patients (8.7%) had unsuccessful attempts, 11 (7.3%) of them had failure of deployment of the device, while embolization of the device occurred in two of the patients (1.3%). CONCLUSIONS: Amplatzer duct occluder device is safe and effective for closure of different types and sizes of PDA with low rate of complication.
