Safe Technique of Coronary Button Preparation in Redo Bentall Operation

We introduce a technique of coronary button reconstruction in performing a redo Bentall procedure. A coronary button is prepared leaving a 3 to 4 mm rim of old Dacron graft surrounding the previous button. The Dacron rim may be sewn to the new aortic root graft directly or via an interposed 8- or 10-mm graft, using a modified Cabrol technique. If the button is comprised of good tissue and can be well-mobilized, it is removed from the Dacron rim and anastomosed directly to the new Dacron graft.
