title: Infective endocarditis--a forgotten cause for heart insufficiency in elderly. Case report.
abstract: Right heart infective endocarditis in an elderly patient with no previous known risk factors is a very rare situation (even if subacute infective endocarditis has the same chance of occurrence at either a young person, or an elderly patient). We present the case of a 75-years old patient, with no previous cardiac history, addressed to our clinic with nonspecific septic symptoms associated with an edematous syndrome. The patient was treated for right heart valve infective endocarditis; a particularity may be the fact not all Duke criteria were respected. Iatrogeny was involved, our patient having administered a 7-day antibiotic treatment before hospital addressing. The therapeutic probe was positive: excellent evolution under treatment. Few cases of infective endocarditis of the tricuspid valve were reported worldwide, in which the source of infection was unknown in about 80% of cases. In two pediatric cases reported, tricuspid endocarditis was caused by Staphylococcus aureus septicemia following upper respiratory infection. This may also occur in adult cases. Further investigations should be carried out in the future to elucidate the source of infection. Isolated right-sided endocarditis should be included in the differential diagnosis of patients with febrile syndrome, respiratory symptoms and predisposing disease, even when they do not have a pacemaker and are not intravenous-drug users (IVDU).
