Annually, many operations for repeat prosthetic reconstruction of the pulmonary artery valve are performed due to dysfunction after primary correction of both congenital and acquired heart defects. Open operations with artificial circulation are associated with a high surgical risk. Transcatheter implantation is a new and progressive technique of heart valve replacement. Until recently, implantation of only a biological graft in the position of a pulmonary artery valve was possible, but a limited service life and high risk of the development of infective endocarditis stimulate search for new solutions of this problem.

In the he present work we describe cases concerning placement of the first Russian-made valve-containing stent in the position of the pulmonary artery, with the stent’s closing mechanism made of polytetrafluoroethylene thus giving ground to count on more favourable results.

KEY WORDS: transcatheter valve implantation, pulmonary artery valve prosthetic reconstruction, transventricular approach, tetralogy of Fallot.
