Ductal stenting to improve pulmonary blood flow in pulmonary atresia with intact ventricular septum and critical pulmonary stenosis after balloon valvuloplasty.

Stenting the arterial duct in pulmonary atresia with intact ventricular septum or critical pulmonary stenosis is a feasible, safe, and efficient technique. It avoids surgery or long hospital stay with prostaglandin infusion. The minimal 6 months stent longevity provides a period of time long enough to decide whether the right ventricular diastolic function is normalised or Glenn surgery is still needed.
