Outcomes of surgery in the treatment of isolated nonnative mitral valve infective endocarditis.

摘要: Objective We reviewed our experience with the operative management of patients isolated nonnative mitral valve infective endocarditis to better understand outcome. Methods records 39 operated on for from January 1974 June 2009. Median age group was 68 years. There were 23 (59%) women. Prostheses mechanical in 18 (46%) patients, biological (46%), and annuloplasty rings 3 (8%). Staphylococcus present 22 (56%) patients. Operative indications included dysfunction 26 (67%) heart failure (56%). Results Perivalvular abscess 12 (31%) Replacement valves 16 (41%). Twenty (51%) received additional procedures. Treatment-related mortality occurred 8 (21%) being only factor predictive (hazard ratio, 5.37). Follow-up survivors 5.7 Six (18%) underwent repeat valve replacement including who had an annulus at initial operation 2 prosthesis sutured left atrial wall. 1 (4%) case recurrent 28 who survived more than year after incident operation. Survival 5 years 48% (95% confidence interval, 35%-67%). Conclusions Surgery carries increased risk. Aggressive debridement reconstruction are paramount achieving a good Surviving obtain high rates cure freedom endocarditis.
