Brucella endocarditis, although a rare complication of brucellosis, is the main cause of death related to this disease. This report describes a case of aortic endocarditis due to Brucella abortus in an elderly farmer with known aortic stenosis. Urgent valve replacement was performed because of progressive heart failure despite appropriate antimicrobial treatment. The infection was cured with trimethoprim-sulfamethoxazole and rifampin given for 3 months after surgery. A review of the literature reports on the 38 other cases of cured brucella endocarditis made clear the need for combined antimicrobial treatment and surgical valve replacement.
