title: Transcatheter device closure of patent ductus arteriosus.
abstract: OBJECTIVE
  To determine the efficacy, safety and immediate complications encountered during percutaneous device closure of patent ductus arteriosus (PDA).
  
  
  METHODS
  Case series.
  
  
  METHODS
  Department of Paediatric Cardiology, AFIC/NIHD, Rawalpindi, from January 2005 to December 2010.
  
  
  METHODS
  Consecutive 500 patients who underwent attempted transcatheter PDA device closure were included in the study. Device type position, success of closure and complications were described as frequency percentage.
  
  
  RESULTS
  In 491 cases (98.2%), PDA was successfully occluded including 4 cases (0.8%) where devices were dislodged but retrieved and redeployed in Cath laboratory. PDA occluder devices used in 448 cases (91%) while coils (single or multiple) were used in 42 cases (8.5%) and in one case (0.2%) ASD occluder device was used to occlude the PDA. There were 09 (1.8%) unsuccessful cases, 06 (1.2%) were abandoned as ducts were considered unsuitable for device closure, 02 (0.4%) devices dislodged and needed surgical retrieval and one case (0.2%) was abandoned due to faulty equipment. The narrowest PDA diameter ranged from 0.5-14 mm with mean of 4.5±2.4 mm. There was a single (0.2%) mortality.
  
  
  CONCLUSIONS
  Transcatheter occlusion of PDA by coil or occluder device is an effective therapeutic option with high success rate. Complication rate is low in the hands of skilled operators yet paediatric cardiac surgical back-up cover is mandatory.
