Acute Type A Dissection 18 Years After a Ross Operation: The Old Prejudice

An acute aortic dissection of the pulmonary autograft with a free rupture of the neoaortic wall is a rare complication after a Ross procedure. In this case, the intimal tear was localized in the noncoronary sinus of the pulmonary autograft and the neoaortic wall was ruptured in the involved sinus area. The dissection was contained in the pulmonary autograft. This report describes a successful aortic root replacement of a patient with the clinical symptoms of an acute aortic type A dissection with a free rupture of the neoaortic wall.
