Abstract
Surgical correction in patients with congenital heart disease requires different types of conduits for connection of a right ventricle outflow
tract with the pulmonary artery. It is known that conduits, currently used for the right ventricle outflow tract reconstruction in
patients with congenital heart disease, eventually often undergo dysfunction. Homografts and allografts prone to calcification and
subsequent stenosis. Synthetic prosthesis stenosis is caused by neointimal proliferation that thereafter leads to their surgical replacement. Balloon dilatation and stenting are potentially effective in case of conduit stenosis, whereupon surgical replacement of the conduit can be delayed for two or more years.
