title: Chronic type A dissection in a pulmonary autograft.
abstract: A 37-year-old patient presented with severe aortic valve insufficiency due to massive dilatation of the neo-aortic root (77 mm diameter) 14 years after a Ross procedure. Intraoperatively, the dilatation appeared to be caused by a localized chronic dissection of the pulmonary autograft. Surgery consisted of a modified Bentall procedure with a mechanical composite valve, with an uncomplicated postoperative course.
