Outcomes of surgical intervention for isolated active mitral valve endocarditis

摘要: Objective Although several studies have examined the outcomes of mitral valve repair for infective endocarditis, no documented long-term surgical intervention active endocarditis confined to valve. Methods One hundred four patients underwent over a 27-year period (mean age, 50 ± 18 years; 52% female). The infected was native in 81 patients, previously repaired 6 and prosthetic 17 patients. Staphylococcus aureus most commonly isolated (32%) source infection. Twenty-eight (27%) had annular abscesses. Surgical consisted or replacement limited infection radical resection, patch reconstruction, abscess. Mean follow-up 5.6 4.4 years (range, 0–20 years) complete. Results There were 9 (8.7%) in-hospital deaths 28 late deaths. Overall survival at 5, 7, 10 73% 5%, 68% 58% 6%, respectively. At 7 years, freedom from recurrent 89% 4% reoperation 94% 3%. Event-free 60% 6% 46% 7%, respectively, significantly higher with versus those nonnative (ie, repaired; years: 63% 7% vs 50% 12%, P S infection, bioprosthesis insertion independent predictors death all causes. group older (57 20 44 15 mechanical 46 12 group, = .003). Conclusions remains difficult, high morbidity mortality long term. is worse who endocarditis.
