15-year comparison of supra-annular porcine and PERIMOUNT aortic bioprostheses.
2006
The second-generation Carpentier-Edwards bioprostheses, the supra-annular porcine valve and the PERIMOUNT pericardial valve, have been evaluated longitudinally for several years. This study compared clinical performance over 15 years. Aortic valve replacement was performed with a supra-annular porcine valve in 1,823 patients (group 1) aged 19–89 years (mean, 68.9 ± 10.9 years) and with a PERIMOUNT pericardial bioprosthesis in 1,430 patients (group 2) aged 16–90 years (mean, 69.5 ± 10.4 years). The groups were similar except for concomitant coronary artery bypass in 43% of group 1 and 18% of group 2 (p 60 years, between the groups, but was dissimilar (group 2 > group 1) for age ≤ 60...
