title: Isolated Streptococcus agalactiae tricuspid endocarditis in elderly patient without known predisposing factors: Case report and review of the literature.
abstract: Group B streptococcal (GBS) tricuspid infective endocarditis is a very rare clinical entity. It affects intravenous drug users, pregnant, postpartum women, and the elderly. We report the case of a 68-year-old patient without known predisposing factors who presented a GBS tricuspid endocarditis treated by penicillin and aminoglycosides with no response. The patient was operated with a good evolution. Our case is the 25th reported in the literature. GBS disease is increasing in the elderly and is mainly associated to comorbid conditions. Tricuspid infective endocarditis with Group B streptococcus predominantly presents as a persistent fever with respiratory symptoms due to pulmonary embolism. Therefore, it requires a medicosurgical treatment and close follow-up.
