Presented at Aortic Surgery Symposium X, New York, NY, April 27–28, 2006.

BACKGROUND: Combined aortic valve repair and aortic valve–sparing surgery requires an approach determined by the leaflets and aortic root anatomy.

METHODS: Among patients referred for aortic root aneurysm, 114 patients underwent an aortic valve–sparing procedure in which a reimplantation or remodelling technique was used. The Gelweave Valsalva prosthesis (Sulzer Vascutek, Renfrewshire, UK) was used in 45 patients. Better molding of the prosthesis on the aortic annulus was achieved by a low proximal dissection and incisions on the prosthesis to respect the anatomy of the aortoventricular junction. The reimplantation technique was used in 58%, and 62% of all patients underwent an associated leaflet procedure.

RESULTS: The operative mortality rate was 1%, with a 2% immediate reoperation rate. During the mean follow-up 50 ± 35 months, 3 patients (2.6%) needed reoperation for recurrent aortic regurgitation (n = 2) or aortic stenosis (n = 1). At the end of follow-up, aortic regurgitation grade exceeding 2 had occurred in 2.6% of patients (n = 3), and 98.2% were in New York Heart Association functional class 1 or 2. Neither the early nor mid-term results showed any differences among the different surgical techniques used (reimplantation, remodeling, Valsalva prosthesis, additional leaflet repair).

CONCLUSIONS: A complete approach to the different components of the aortic root allows good clinical results at mid-term.
