title: Aortic root abscess complicated by fistulization and intracerebral hemorrhagic infarction.
abstract: We report an unusual case of a 12-year-old male with aortic root abscess complicated by fistulization and intracerebral hemorrhagic infarction. Transesophageal echocardiography provided exact information about the location and dimension. Color-flow mapping demonstrated fistulous communication between the abscess and both the aorta and the left ventricle, causing severe diastolic regurgitation through the paravalvular leak. Pulmonary autograft aortic root replacement was performed with good result.
