Treatment of endocarditis with valve replacement: the question of tissue versus mechanical prosthesis

摘要: Abstract Background . It remains unknown whether there is any important clinical advantage to the use of either a bioprosthetic or mechanical valve for patients with native prosthetic endocarditis. Methods Between 1964 and 1995, 306 underwent replacement left-sided (209 patients) (97 Mechanical valves were implanted in 65 patients, bioprostheses 221 homografts 20 patients. Results Operative mortality was 18 ± 2% independent type ( p > 0.74). Long-term survival superior endocarditis (44 5% at years) compared those (16 7% 0.27). The long-term freedom from reoperation who received biologic younger than 60 years age low (51 10 years, 19 6% 15 years). For older however, biological (84 similar that all (74 9% 0.64). Conclusions are most suitable endocarditis; tissue acceptable greater infections selected because their limited life expectancy.
