[Early surgery in patients with native valve endocarditis]. / Chirurgie de l'endocardite sur valves natives à la phase active.

ABSTRACT

Between January 1990 and December 2006, 93 patients with infective endocarditis on native valves were operated in the active phase of the disease. The average age of our patients was 32 years with a male ascendancy. The causal heart disorder was found in 89 % of the cases, dominated by rheumatoid arthritis. The germ in cause was isolated in 52.6 % of the cases. The operative indication was hemodynamic in 29 cases, infectious in nine cases, mixed in 29 cases and embolic in 26 cases. The average operating delay was of 13 days with regard to the beginning of the antibiotic treatment. We realized a valvular aortic replacement at 32 patients with reconstruction of the ring in six cases, a valvular mitral replacement at 29 patients, a mitroaortic replacement at 21 patients, a reconstructive mitral surgery in nine cases, a valvular tricuspid replacement in one case and a reconstructive tricuspid surgery in one case. The early mortality was 13 %. The follow-up was 89 % with an average recession of 3.1 years and a late mortality of 5 %. The aim of this study is to analyze the immediate and late results of the surgery of infective endocarditis in the active phase and to bring to light the prognostic factors of mortality.
