A 34-year-old woman who was suffering from aortitis syndrome with annuloaortic ectasia (AAE) and severe aortic regurgitation (AR) from 18 years of age was admitted for an aortic root replacement. She has been on 5mg predonine daily. Aortography, CT and echocardiography examinations revealed dilated aortic annulus（D＝30mm）and valsalva sinuses（D＝43mm）and overstretched aortic valve leaflets. The ascending aorta was aneurysmal (D=50mm). Because of the patient's strong desire to have children, a Freestyle bioprosthesis was chosen for replacement. A collagen impregnated tube graft was interposed between the Freestyle and the proximal end of the transverse aorta. In order to reconstruct the coronary arteries, the Cabrol technique was utilized because of severe inflammatory adhesion of the aortic root. The patient had an uneventful postoperative course. This case shows that an aortic root replacement with Freestyle bioprosthesis offers a great benefit to those patients who are not suitable to receive postoperative anti-coagulation therapy to enable future pregnancy and child delivery.
