Stents are used in pediatric cardiology for a large variety of indications, but most often to enlarge stenotic vessels resulting in a defined diameter, as the elastic recoil of currently used stents is minimal. Experimentally, stents are used as a carrier for the implantation of valves or vessels, investigative is the use of stents as an occlusive device. Several novel indications have evolved for stents in pediatric cardiology: stenting of aortopulmonary collateral arteries, stenting of the ductus arteriosus in duct dependent congenital heart disease, stenting of the right ventricular outflow tract, and the use of stents to perform interventional completion of univentricular circulation.
