Surgical approach to the management of Brucella endocarditis.

OBJECTIVE: Brucella endocarditis is a rare complication of Brucella infection; however, it is the major cause of deaths in those infected with this disease. In this study, we aim to discuss the results of seven cases who underwent surgery for Brucella endocarditis in our clinic using the knowledge gathered through the literature. METHODS: We reviewed seven patients with Brucella endocarditis, who underwent surgery in our department between October 1990 and April 2007. Brucella endocarditis was diagnosed by physical examination, laboratory findings, serological tests, blood culture, transthoracic and trans-oesophageal echocardiography. All cases underwent surgery after 4-6 weeks of medical therapy. Antimicrobial treatment was maintained for an average of 6 months after surgery. The mean follow-up was 27.4 months. RESULTS: The mean age was 30 years (range, 5-47 years). Four of the patients were male. Of the cases, aortic valve replacement (AVR) was performed in three, mitral valve replacement (MVR) was performed in three and combined aortic and mitral valve replacement (AVR+MVR) was performed in one patient. Pericardial tube drainage was done in one patient because of pericardial effusion and cardiac tamponade that developed 13 days after surgery. One (14.3%) of our patients died 15 days after surgery. The others were discharged. CONCLUSIONS: We concluded that medical and surgical treatment had to be performed simultaneously for the successful management of Brucella endocarditis, a fatal complication of Brucella infection.
