[Destructive endocarditis caused by Streptococcus sanguis on normal valves after gastroduodenoscopy].

In recent years, epidemiological and clinical patterns in infective endocarditis are changed: mean age of patients, sex, underlying cardiac diseases, source of bacteremia, availability of better diagnostic methods--specially two-dimensional and doppler echocardiography--and surgical options. The Authors report a paradigmatic case of a young man without cardiac disease, who developed a destructive endocarditis complicated by refractory congestive heart failure; the cause was an organism of low pathogenicity, Streptococcus sanguis, that entered the bloodstream after gastroduodenoscopy.
