[Surgical treatment of active infective endocarditis with aortic root abscess, left ventricular and right atrial fistulae--report of a child].

Aortic valve replacement with a 17 mm Björk-Shiley prosthetic valve, and the closure of left ventricular and right atrial fistulae which were connected with the aortic root were successfully performed in a 10-year-old boy. He was admitted because of high fever and severe heart failure, and diagnosed aortic regurgitation, and left ventricular and right atrial fistulae due to active infective endocarditis. The annular defect was repaired with annular enlargement by a pericardial patch and annulo-right atrial fistula was directly closed from the right atrium. The patient is doing well 1 year after surgery.
