The "button inside" technique for the aortic root replacement: a modified button technique.
Modified button technique for reattachment of coronary arteries in the aortic root replacement is reported. Anastomosis of the coronary buttons is performed from the inside of the composite valve graft previously including the coronary buttons in the composite valve graft. Reduced tension is present between coronary arteries and the composite valve graft once the heart is beating and the systemic pressure is increasing. In this way coronary buttons are reinforced directly by the composite aortic wall graft prosthesis. The coronary ostia are perfused with lower tension at the site of the coronary anastomoses. No bleeding from the suture line of the coronary buttons occurs using this new surgical approach.
