Endocarditis caused by B fragilis

A 54-year-old man had had an acute anterior myocardial infarction nine years prior to this hospital admission. Since that time he had been asymptomatic with the exception of occasional episodes of precordial chest pain. The patient died from septic shock on the tenth day after the present admission. On autopsy there was an old myocardial infarct with aneurysmal dilatation of the left ventricle which contained a large thrombus with multiple abscesses. Septic infarcts were also found in the left kidney and the left temporal lobe of the brain.
