Abstract
The ''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.
