[Nonbacterial thrombotic endocarditis]. / Endocardite trombótica não-bacteriana.

A case of a 38 year-old female patient admitted to the hospital with stroke is reported. Transesophageal echodoppler cardiogram showed mitral valve prolapse associated with a vegetation on its anterior leaflet, and this vegetation was a possible embolic source. The follow-up without signs of infectious disease, the good clinical outcome and the regression of the valvar vegetation without use of antibiotics consolidated the diagnosis of nonbacterial thrombotic endocarditis. As far as it is known, this is the first reported case with antemortem diagnosis and good outcome with treatment with aspirin and ticlopidine.
