The Ross procedure includes removal of the malformed aortic valve and replacement of a pulmonary autograft in the aortic position. We report a patient with bicuspid aortic valve malformations and aortic annulus dilatation, who had saccular-form, true-type, aneurysm in pulmonary autograft seven months after the Ross procedure. These changes have not been described as complications Pathologically, a marked degeneration was noted in the tunica media of the aneurysm, as well as in the original aortic root. These findings may suggest similar pathological characteristics in patients with congenital aortic valve malformation.
