Key result
Root remodelling with extra-aortic ring annuloplasty yielded similar 5-year survival free from aortic insufficiency ≥2 or reoperation compared to reimplantation (84% vs 83%; P=0.62).

Does root remodelling with extra-aortic ring annuloplasty improve mid-term outcomes compared to reimplantation in patients undergoing valve-sparing aortic root replacement?
Absolute Event Rate: 84% vs 83%
p-value: p=0.62
Mid-term outcomes after root remodelling with extra-aortic annuloplasty are comparable to reimplantation, demonstrating its effectiveness in stabilizing annular dimensions.
Lenoir et al. (2018) conducted a cohort in Valve-sparing aortic root replacement (n=142). Root remodelling with extra-aortic ring annuloplasty vs. Reimplantation technique was evaluated on 5-year survival free from aortic insufficiency ≥2 or reoperation (p=0.62). Root remodelling with extra-aortic ring annuloplasty yielded similar 5-year survival free from aortic insufficiency ≥2 or reoperation compared to reimplantation (84% vs 83%; P=0.62).
