Why the study?
The study was conducted to assess early and mid-term outcomes of two aortic root surgeries for aortic regurgitation with aortic root or ascending aortic aneurysm.
Does valve-sparing root reimplantation improve survival and reduce complications compared to the mechanical Bentall procedure in patients <70 years old with aortic root aneurysm?
Population
626 patients <70 years old undergoing elective aortic root surgery
Comparison
Reimplantation vs mechanical Bentall
Design
Prospective cohort study
Follow-up
Mean 27 months (11 - 40 months)
Key result
Valve-sparing root reimplantation was associated with a significantly lower risk of anticoagulant-related hemorrhage compared to mechanical Bentall procedures (HR 0.13; p=0.0045).

Reimplantation showed comparable short-term survival to mechanical Bentall after propensity adjustment; leaves open long-term valve durability and reintervention rates in younger adults.

Does valve-sparing root reimplantation improve survival and reduce complications compared to the mechanical Bentall procedure in patients <70 years old with aortic root aneurysm?
Hazard Ratio: 0.13
Absolute Event Rate: 0.4% vs 3.48%

Valve-sparing root reimplantation is a safe and effective alternative to the mechanical Bentall procedure for aortic root aneurysms, offering excellent survival and significantly lower risks of anticoagulant-related hemorrhage.
Sun et al. (2026) conducted a cohort in Aortic regurgitation with aortic root/ascending aortic aneurysm (n=626). Valve-sparing root reimplantation vs. Mechanical Bentall procedure was evaluated on Anticoagulant-related hemorrhage (HR 0.13, p=0.0045). Valve-sparing root reimplantation was associated with a significantly lower risk of anticoagulant-related hemorrhage compared to mechanical Bentall procedures (HR 0.13; p=0.0045).
