[Non-infectious thrombotic endocarditis: a case report]. / Endocardite trombótica não infecciosa: a propósito de um caso clínico.

ABSTRACT

A 48 year-old female patient, admitted with an ischemic stroke, had a transesophageal echocardiogram (TEE) that revealed a dense vegetation in the noncoronary aortic cusp, which was considered the probable source of embolism. The clinical investigation did not identify any other disease or infectious process. However the lack of histologic proof, the absence of fever, the fact that the blood cultures were persistently negative, the patient recovery with no need of antibiotics, and the results of the TEE, are highly suggestive of the presence of a non infectious thrombotic endocarditis. After 18 months of anti-platelet treatment, the patient showed no new embolic episodes and TEE demonstrated the resolution of the vegetation.
