Notes:
A newborn with pulmonary atresia with intact ventricular septum (PA-IVS) was treated with radiofrequency current perforation of the atretic pulmonary valve. As the right ventricle was hypoplastic (z-value of the tricuspid valve: —4) the arterial duct was stented with a Gianturco-Roubin GR II stent. Early postinterventionally, the patient became cyunotic and compromised blood flow across the stented ductus arteriosus despite adequate stent position was detected echographically. The newborn was treated successfully with the implantation of a Palmaz stent (Johnson & Johnson Interventional Systems, Warren, NJ, USA) into the obstructed Gianturco-Roubin GR II stent. The Gianturco-Roubin GR II stents might be associated with the risk of early stent stenosis after implantation in actively contracting tissues like the ductus arteriosus. In patients with early stent stenosis after ductal stenting, bailout implantation of a subsequent stent can be performed. Transcatheter procedures can be effective means for therapy of PA-IVS.
