Questions of the occurrence of transprosthesis regurgitation after transcathether prosthetization of the aortic valve are discussed. We present results from hydrodynamic tests of prototype transcatheter aortic valve prostheses with different methods of attachment of the valve leaflets in conditions of deformation of the fibrous ring. Prototype prostheses with attachment of the leaflets of the valve apparatus above the seating zone of the frame of the prosthesis demonstrated optimal hydrodynamic characteristics.
