button Bentall technique
A modified surgical approach where coronary arteries are reimplanted as 'buttons' of aortic wall tissue during aortic root replacement.
Full Definition
The button Bentall technique is a refined surgical modification of the standard Bentall procedure, involving the reimplantation of coronary arteries along with surrounding aortic wall tissue (coronary 'buttons') during composite aortic root replacement. This technique preserves more native coronary anatomy compared to direct coronary reimplantation methods and may reduce the risk of coronary anastomotic complications. The procedure involves careful excision of coronary ostia with adequate surrounding aortic tissue, followed by direct anastomosis to the prosthetic graft. This approach is particularly valuable in cases with complex coronary anatomy or when coronary artery mobilization is limited. The technique requires precise surgical planning to ensure adequate tissue margins while avoiding excessive button size that could compromise the repair.
Usage
Usage note: Distinguish from the general Bentall procedure; specifically refers to the coronary reimplantation methodology using aortic wall buttons.
