    Abstract:
    A rare case of a pseudoaneurysm from the mitral-aortic intervalvular fibrosa following bacterial endocarditis in a 17-year-old male is presented. Destructive infection secondarily involved the mitral-aortic intervalvular fibrosa. Perforation of this portion resulted in the formation of the pseudoaneurysm situated at the base of the left ventricle between the aorta and the left atrium. With echocardiography, computed topography, angiography, and magnetic resonance imaging (MRI), a pseudoaneurysm was diagnosed. MRI especially revealed detailed information and the extension of pseudoaneurysm. Our patient underwent resection of the pseudoaneurysm, reconstruction of left ventricular outflow with glutaraldehyde-preserved bovine pericardium, and replacement of the aortic valve. His postoperative course was uneventful. No recurrence of endocarditis was detected in the following year.
