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 ...
متن کاملEarly Doppler-echocardiography evaluation of Carpentier-Edwards Standard and Carpentier-Edwards Magna aortic prosthetic valve: comparison of hemodynamic performance
OBJECTIVES This study was designed to describe Doppler-echocardiography values of Carpentier-Edwards Perimount Standard (CEPS) and Carpentier-Edwards Perimount Magna (CEPM) aortic prosthetic valves, evaluated by a single, experienced echo-laboratory, early in the postoperative phase. METHODS Three-hundred-seventy-seven consecutive patients, who had had a CEPS or a CEPM implanted in our Hospit...
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...
متن کاملHemodynamic results of aortic valvular replacement with the porcine xenograft valve.
Twenty-three patients were evaluated by cardiac catheterization two to 12 months following aortic valve replacement with the porcine xenograft valve. These hemodynamic studies established a mean peak-to-peak systolic gradient across the prosthesis of 23 mm Hg with a range of 6-58 mm Hg. The mean effective orifice area was calculated to be 1.25 cm2. The effective orifice area increased with incr...
متن کاملInitial experience of mitral valve repair using the Carpentier-Edwards Physio II annuloplasty ring.
OBJECTIVE The Carpentier-Edwards (CE) Physio II ring is a new prosthetic ring designed to accommodate the changing pathology seen in the spectrum of degenerative valve disease, particularly the larger anterior leaflet in repair of the Barlow valve. The aim of our study was to assess the safety and efficacy of mitral valve (MV) repair with the CE Physio II ring. METHODS Between April 2009 and ...
