[Ductus arteriosus patency with stenting in critical pulmonary stenosis and pulmonary atresia with intact interventricular septum].

We report our experience with stenting of the ductus arteriosus in three neonates. Two patients had pulmonary atresia with an intact interventricular septum and one had critical pulmonary stenosis. Radiofrequency ablation was used to open the atretic pulmonary valve in two patients. In all three patients implanting a stent avoided the need for surgical creation of a Blalock-Taussig shunt. In two patients the procedure was scheduled as elective surgery, and in one it was done as an emergency procedure. Ductus arteriosus stenting is an alternative to palliative cardiac surgery.
