title: Transcatheter Treatment of Large Aortopulmonary Window: A Case Report.
abstract: BACKGROUND
  Aortopulmonary window (APW), a large aortopulmonary septal defect (APSD), is a serious and rare defect within congenital heart diseases.
  
  
  METHODS
  In this study, we reported an APW case with severe pulmonary arterial hypertension. This patient was successfully treated by transcatheter closure with a muscular ventricular septal defect (VSD) occluder.
  
  
  CONCLUSIONS
  We had a successful experience with transcatheter closure of a large APW using a muscular VSD occluder. There was no residual shunt or complications during the 6-month follow-up.
