[Clinical follow-up of patients after valve replacement with Omniscience cardiac valves: can this valve be recommended? (author's transl)].

Clinical evaluation of 9 patients, after valve replacement with Omniscience cardiac valves (5 with aortic, 4 with mitral valve replacement) showed opening angles significantly lesser than the theoretical in-vitro valve of 80 degrees opening angles were essential by cineangiography. In 3 of 4 patients with mitral valve replacement, reoperation became necessary due to prosthetic valve dysfunction. Thus the implantation of Omniscience cardiac valves cannot be recommended.
