First-in-human implantation of a novel self-expanding supra-annular transcatheter heart valve for transcatheter aortic valve implantation inside a small degenerated aortic surgical bioprosthesis

摘要

With next-generation valves such as the ALLEGRA valve from NewValve Technologies (NVT), Hechingen Germany, there is a very likely treatment expansion for patients with aortic valve disease. Besides treatment of native valvular aortic stenosis with the ALLEGRA valve, the special implant mechanism seems to be an appealing concept for patients with degenerated surgical bioprostheses. We report the first case of a transfemoral implantation in small degenerated surgical bioprosthesis of a 76-year-old woman.
