title: Transcatheter closure of an atrial septal defect in a newborn with aortic stenosis.
abstract: OBJECTIVE
  A newborn with valvular aortic stenosis and a 5 mm atrial septal defect (ASD) underwent emergency aortic valvotomy. The small left ventricle of the newborn with signs of fibroelastosis showed good function but a reduced compliance and caused a large left to right shunt at atrial level.
  
  
  RESULTS
  As the patient became respirator-dependant the ASD was interventionally closed with an 18 mm Amplatzer PFO occluder. The patient could be weaned from the ventilator within two days and had an uneventful recovery.
  
  
  CONCLUSIONS
  Interventional closure of an ASD is possible even in the newborn period and should be considered as an alternative to surgery.
