[Myocardial infarction as a consequence of infective endocarditis in valvar bioprosthesis].

A sixteen year-old male, followed in the Unicamp Cardiology Clinic with a previous record of rheumatic heart disease and a biological mitral prosthesis, presented with infective endocarditis. In spite of a good initial response to antibiotic therapy, the patient died in two weeks. Autopsy disclosed endocarditis of the prosthetic valve and embolic occlusion of the circumflex branch of left coronary artery.
