摘要: Abstract Background . The Carpentier-Edwards standard porcine bioprosthesis experience to 21 years has been evaluated determine the influence of structural valve deterioration by position in various age groupings. Methods From 1975 1988, 1,181 patients had prosthesis implanted 1,198 procedures. mean population was 57.9 ± 12.5 (range, 85 years). Aortic replacement performed 564 (47.8%); mitral replacement, 478 (40.5%); and multiple 132 (11.2%). Concomitant procedures were 337 (28.5%), 140 (11.9%) previous operations. Results early mortality 8.1% (97), only 0.4% (5) which valve-related. total follow-up 10,405 (mean, 8.8 5.2 late 5.7%/patient-year (591), with valve-related component 1.6%/patient-year (168) a 13% reoperative (56). linearized rate 3.8%/patient-year (395), overall complications 7.1%/patient-year (737). survival at 20 17.2% 3.1% ( p Conclusions is recommended for aortic older than 70 61 (when extended longevity not anticipated) years.
