The modified Bentall procedure for aortic root replacement

ABSTRACT
- THE BENTALL PROCEDURE is a surgical repair of an ascending aortic or aortic root aneurysm in combination with aortic valve disease. Less commonly, it is used to repair aortic dissection affecting the aortic root and valve.
- DURING THE PROCEDURE, a composite aortic valve graft is used to replace the proximal ascending aorta and aortic valve.The procedure is performed through a median sternotomy during cardiopulmonary bypass.
- IN THIS MODIFICATION of the original procedure, coronary artery circulation is maintained by removing a full-thickness “button” of aorta surrounding the coronary ostia, making it easier to implant the proximal end of the coronary arteries into openings made in the aortic vascular graft.AORN J 84 (July 2006) 52-70.
