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 3 neonates. Two patients had pulmonary atresia with an intact interventricular septum and 1 had critical pulmonary stenosis. Radiofrequency ablation was used to open the atretic pulmonary valve in 2 patients. In all 3 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 1 it was done as an emergency procedure. Ductus arteriosus stenting is an alternative to palliative cardiac surgery.
