Enterococcal infective endocarditis on native aortic valve

Enterococcal endocarditis accounts for 10% of all bacterial endocardits. The infection progresses in a subacute way and when localized on the aortic valve it has a very poor prognosis since the valve is usually destroyed being death the fatal outcome. We report a case of a patient with infective endocarditis resulting from the implantion of the Enterococcus on the native aortic valve. Nor visk factors or an apparent main gate could be found. The patient was hospitalized after several months of a non especific febrile syndrome. The literature is reviewed. Diagnostic tests and clinical signs are discussed making emphasis on the refractoriness to chemotherapy.
