Key result
Valve-sparing aortic root replacement using the reimplantation technique resulted in 89% overall survival and 91% freedom from reoperation at 10 years, with no difference in outcomes between tricuspid and bicuspid aortic valves.
Why the study?
Current guidelines recommend valve-sparing aortic root replacement, but reported outcomes for the reimplantation technique derived mostly from single-center studies, and potential differences for bicuspid aortic valve phenotype remained unclear.

Supports reimplantation VSRR for root aneurysm with durable survival and low reoperation; reinforces guidelines across tricuspid and bicuspid valves.
Meta-Analysis (n=7,878)
Valve-sparing aortic root replacement using the reimplantation technique demonstrates excellent long-term survival and freedom from reoperation, with comparable outcomes for both tricuspid and bicuspid aortic valves.
Mastrobuoni et al. (2023) conducted a meta-analysis in Aortic root aneurysm (n=7,878). Valve-sparing aortic root replacement (reimplantation/David technique) was evaluated on Overall survival at 10 years. Valve-sparing aortic root replacement using the reimplantation technique resulted in 89% overall survival and 91% freedom from reoperation at 10 years, with no difference in outcomes between tricuspid and bicuspid aortic valves.
