Patent ductus arteriosus endovascular closure by amplatzer duct occluder

Transcatheter occlusion of patent ductus arteriosus (PDA) using various occluding devices and coils is a widely accepted alternative to surgical closure in most pediatric cardiology centers. In spite of these advantages in transcatheter management, the occlusion of the moderate and the large PDA remains a challenge. The Amplatzer Duct Occluder (ADO) (AGA Medical, Golden Valley, MN, USA) is a new device with easy placement. It is reported to have higher rates of occlusion than other occluders currently available for transcatheter closure of PDA. 18 patients (6 male and 12 female) underwent transcatheter closure of PDA using the ADO. The mean PDA minimal diameter (pulmonary end) was 5,4+/-2,8 mm (range 4,0 mm-12 mm). We do not use ADO for small PDA closure (
