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 (

Comparison of surgical and by transcatheter methods of closure of atrial septal defect based on the two year experience.

Our study was designed to compare surgical and transcatheter methods of treatment of frequent congenital malformation: atrial septal defect. Overall, during two year period 45 patients enrolled this study. 36 where referred to surgical treatment, 9 - to interventional. In most of the cases the choice of treatment method was made pre procedurally based on malformation anatomy. Both correction methods proved to be safe and effective. As our study shows the closure success rate is identical for both methods for appropriately selected patients. Residual shunts where haemodynamically insignificant and never needed re-operation. Both procedures have approximately similar major complication prevalence. The main differences were absence of the need for blood transfusion products, morbidity, and length of hospital stay, as well as the cost of treatment. All of them are in favour of Amplatzer device closure. Based on this information we can conclude that all patients feasible for transcatheter treatment should be treated by means of this procedure.
