title: Are the AMPLATZER Duct Occluder II Additional Sizes devices dedicated only for smaller children?
abstract: OBJECTIVE
  The aim of this study was to present our experience with the AMPLATZER Duct Occluder II Additional Sizes (ADOIIAS) for the closure of different types of patent ductus arteriosus (PDA) in patients of various age groups.
  
  
  RESULTS
  A group of 103 patients, in whom the PDA (diameter below 3.5 mm) was closed using the ADOIIAS, was analysed. The median age of treated patients was 3.0 years (from 0.1 to 24 years), and 55 patients (53.4%) were older than three years. Ductal anatomy defined by angiography showed type A in 42 patients (40.8%), type C in six patients (5.8%), type D in 21 patients (20.5%), and type E in 34 patients (33.0%). In two cases, embolisation of the device occurred shortly after implantation. Both occluders were retrieved percutaneously. One death occurred in a neonate four days after ADOIIAS implantation (not related to the procedure: multi-organ failure). Total occlusion of PDA was confirmed in all patients the day after the procedure. No protrusion of the device into the aorta or pulmonary artery was observed in any patient during follow-up.
  
  
  CONCLUSIONS
  The use of the ADOIIAS is a good therapeutic option for the treatment of selected PDA. The implant may be successfully substituted for coil implantation in all age groups.
