Hemodynamic evaluation of the Carpentier-Edwards porcine xenograft.
The hemodynamic function of the thin-wall, glutaraldehyde-treated porcine xenograft was evaluated in 37 asymptomatic patients an average of 8 months (range 6-15 months) after operation. Three patients had a double-valve replacement. Cardiac output and simultaneous transvalvular gradients were recorded at rest and during moderate supine exercise. In 25 patients with an aortic bioprosthesis, the ...

An analysis of 211 patients who had porcine xenograft valve replacements at Henry Ford Hospital between October 1971 and March 1974, was accomplished, with 100% follow-up. The follow-up period extended from 60-89 months after implantation. One hundred sixty-seven patients with 192 valves survived the perioperative period and were subjected to life table analysis. Hemodynamically significant por...
متن کاملLong-term clinical evaluation of mitral valve replacement with porcine bioprosthetic valves in dogs.
This study evaluated the long-term clinical performance of newly developed porcine bioprosthetic valves cross-linked with glutaraldehyde and polyepoxy compound for mitral valve replacement (MVR) in dogs. Five beagle dogs underwent MVR using the porcine bioprosthetic valves during cardiopulmonary bypass. Antithrombotic drugs were administered only for one month after MVR. Six months after MVR, t...
متن کاملHancock, and Carpentier-Edwards heart valve prostheses
From 1975 to 1979, 540 patients undergoing valve replacement were entered into a randomized trial and received either a Bjdrk-Shiley (273 patients) or a porcine heterograft prosthesis (initially a Hancock valve [107 patients] and later a Carpentier-Edwards prosthesis [ 160 patients]). Two hundred and sixty-two patients required mitral valve replacement, 210 required aortic valve replacement, 60...
