How to Fix a Self-Assembled Aortic Valve Conduit to the Annulus

Abstract

‘‘Chimney’’ Bentall Procedure in the Small Aortic Root After Prior Aortic Valve OperationsThe Annals of Thoracic SurgeryVol. 110Issue 3PreviewThe ‘‘Chimney’’ Bentall procedure using a self-assembled valve composite graft has been performed in 24 patients with a small aortic root or annulus after previous valve replacement in our center. The mean diameter of the aortic annulus was 19.58 ± 1.8 mm. During the procedure, the mean size of the implanted aortic valve prosthesis was 22.75 ± 1.78 mm. The mean gradient across the aortic valve prosthesis was 11.17 ± 2.24 mm Hg. This technique allows for the implantation of a larger prosthesis in patients with a small aortic annulus or root after previous aortic valve operation and results in good postoperative hemodynamic characteristics and early clinical results.
