Abstract:
An 8-year-old Japanese boy with severe aortic valve regurgitation was treated by the Ross procedure with use of the full root technique. Takayasu's aortoarteritis was diagnosed 2 months after the operation. At 8 months after the operation, follow-up echocardiography revealed an aortic root pseudoaneurysm, which was surgically repaired. At 24 months after operation, the patient continues to receive prednisolone, azathioprine, and cyclophosphamide and is in good health, with good pulmonary autograft function.
