title: [Transcatheter closure of patent ductus arteriosus with the new Amplatzer Duct OccluderII].
abstract: OBJECTIVE
  To evaluate the indications, methodology and results of the transcatheter closure of patent ductus arteriosus (PDA) with the new Amplatzer Duct Occluder II (ADO-II).
  
  
  METHODS
  Totally 51 patients underwent transcatheter closure of PDA with the new ADO-II. The devices were delivered by 4F or 5F sheath through arterial or venous side respectively. The descending aorta angiography and transthoracic echocardiography was performed to evaluate the device position, residual shunt and complications caused by the device during and after implantation.
  
  
  RESULTS
  Forty-nine patients had successful transcatheter closure of the PDA without significant residual shunts and artery obstruction during the short-term follow-up. One patient received the ADO-II dislodgment and first generation ADO re-implantation for the obvious descending aortal obstruction caused by ADO-II. Another patient had the ADO-II dislodgment and left pulmonary artery shaping surgery, because the ADO-II implantation led to obstruction of the left pulmonary artery. Both the obstructions in these two patients were ameliorated afterwards.
  
  
  CONCLUSIONS
  The transcatheter closure using the ADO-II is safe and effective for the non-window type PDA with a small size.
