Key result
Modified aortic root remodeling with aortic annuloplasty (m-Yacoub operation) achieved a 100% survival rate and an 82.5% reoperation-free rate at 5 years, with significant improvement in aortic regurgitation.

The m-Yacoub operation (aortic root remodeling with annuloplasty) provides excellent mid-term survival and freedom from reoperation in patients with preserved aortic valves.
BACKGROUND: A retrospective study was performed to determine the appropriateness of aortic root remodeling with aortic annuloplasty (m-Yacoub operation). METHODS AND RESULTS: A group of 60 patients with aortic valve disease with concomitant dilated or dissected ascending aorta, who underwent surgery between 1997 and 2003, were evaluated. Nineteen patients whose aortic valves were well preserved (mean age: 57.8+/-13.2 years) underwent the m-Yacoub operation with or without aortic valve leaflet suspension. The average follow-up period was 34.5+/-19.0 months. There were no operative or hospital deaths. Preoperatively, 16 patients had grade 4 aortic regurgitation (AR), 2 had grade 3 AR, and 1 had grade 1 AR. At the latest follow-up, 1 patient had grade 2 AR, 11 had grade 1, and 7 had grade 0. At 5-year follow-up the survival rate was 100+/-0.0%, and the reoperation-free rate was 82.5+/-11.3%. CONCLUSION: Where it is possible to preserve the aortic valve, the m-Yacoub operation is an attractive option.

Kazui et al. (2007) conducted an observational in Aortic root aneurysm or ascending aortic aneurysm with aortic regurgitation (n=19). Modified aortic root remodeling with aortic annuloplasty (m-Yacoub operation) was evaluated on 5-year reoperation-free rate. Modified aortic root remodeling with aortic annuloplasty (m-Yacoub operation) achieved a 100% survival rate and an 82.5% reoperation-free rate at 5 years, with significant improvement in aortic regurgitation.
