title: Interventional stent implantation in a child with patent ductus venosus and pulmonary hypertension.
abstract: We report on the rare case of a 4-year-old boy with patent ductus venosus and pulmonary hypertension presenting with progressive fatigue, tachypnoea at rest and tachycardia. Cardiac catheterisation revealed suprasystemic pressure in the pulmonary arteries with severely elevated pulmonary vascular resistance. In order to reduce the diameter of the ductus venosus, a stent was implanted interventionally, which closed, as expected, spontaneously 2 years later. Pulmonary arterial pressure and pulmonary vascular resistance decreased significantly and the general condition of the boy improved dramatically.
  
  
  CONCLUSIONS
  To the best of our knowledge, this represents the first report of successful interventional stent occlusion of a patent ductus venosus associated with severe pulmonary hypertension. The future will tell whether this intervention is curative or represents a bridging procedure for subsequent liver transplantation.
