Endocarditis is a rare and serious complication of brucellosis and is the main cause of death in this pathology. Diagnosis requires a high level of attention, and is based on the association of epidemiological, clinical and serological elements. Echocardiography plays a crucial role in early diagnosis, as well as in identifying a predisposition to heart disease and local complications typical of this pathology. This case study follows a case of Brucella endocarditis involving the aortic valve, in a 39-year-old male, diagnosed in October 2010. Despite being given complete pharmaceutical treatment, in this instance emergency heart surgery was necessary, due to an inability to control the infection and subsequent changes in the patient’s condition, which were leading to congestive heart failure. Aggressive treatment, with surgery performed during a period of active infection, produced good results in the eradication of infection, and in preventing fatal complications. The patient is now fully recovered, and was given triple therapy for brucellosis according to existing recommendations.

SAAEETAK: PoremeEaj dijastoliEke funkcije lijeve klijetke (LK) je jedan od prvih poremeEaja funkcije LK, koji se registriraju prije poremeEaja regionalnog kontraktiliteta, EKG promjena i bola u prsnom koπu, πto bitno mijenja prognozu pacijenata s akutnim koronarnim sindromom. PoremeEaj relaksacije LK Eesto se registrira u pacijenata s akutnim infarktom miokarda (AIM), a poremeEaj krutosti LK u pacijenata s AIM prednje stijenke. Najizraaeenija dijastoliEka abnormalnost uzrokovana ishemijom miokarda je produaeena i usporena relaksacija miokarda. Ehokardiografske tehnike omoguEavaju evaluaciju dijastoliEkog punjenja obje pretklijetke i klijetke.
