Acute Dissection of Ascending Aorta after Aortic Valve Replacement

A 57-year-old man who had aortic insufficiency with mild dilatation (36 mm) of the ascending aorta but no evidence of aortic wall degeneration, developed acute dissection of the ascending aorta 6 months after aortic valve replacement. He underwent successful Dacron graft replacement of the ascending aorta.
