title: Transcatheter stenting of arterial duct in duct-dependent congenital heart disease.
abstract: BACKGROUND
  Critical congenital heart diseases (CHD) are mostly duct-dependent and require stable systemic-pulmonary communication. In order to maintain patency of the ductus arteriosus (DA), the first line treatment is Prostaglandin E1 and the second step is the surgical creation of aortic-pulmonary shunt. To reduce surgical risk in neonates with the critical CHD, transcatheter stenting of DA can be performed in selected cases.
  
  
  METHODS
  A four-month old infant was diagnosed with the pulmonary artery atresia with ventricular septal defect (PAA/VSD). The left pulmonary artery was perfused from DA, and the right lung through three major aortopulmonary collaterals (MAPCAs). A coronary stent was placed in the long and critically stenotic DA, with final arterial duct diameter of 3.5 mm, and significantly increased blood supply to the left lung. After the procedure, the infant's status was improved with regard to arterial oxygen saturation, feeding and weight gain. During the follow-up, one year later, aortography revealed in-stent stenosis. The left pulmonary artery, as well as the branches, was well-developed and the decision was made to proceed with further surgical correction.
  
  
  CONCLUSIONS
  Stenting of DA can be an effective alternative to primary surgical correction in selected patients with duct-dependent CHD.
