Key result
Preoperative aortic root diameter has no impact on 3-year survival after valve-sparing aortic root reimplantation.
Why the study?
Does preoperative aortic root diameter impact long-term aortic valve function and survival after valve-sparing aortic root reimplantation in patients with aortic root aneurysm?
Population
123 patients with aortic root aneurysm undergoing valve-sparing aortic root reimplantation.
Comparison
Preoperative aortic root diameter >60 mm or… vs Preoperative aortic root diameter <50 mm
Design
Cohort
Follow-up
Mean 43+/-26 months, 40+/-25 months, 23+/-19 months

May support valve-sparing reimplantation across preoperative diameters; hypothesis-generating for long-term valve durability.

Does preoperative aortic root diameter impact long-term aortic valve function and survival after valve-sparing aortic root reimplantation in patients with aortic root aneurysm?
Absolute Event Rate: 98% vs 100%
p-value: p=ns
Preoperative aortic root diameter does not impact the longevity of repair or long-term aortic valve function after valve-sparing aortic root reimplantation.
Leyh et al. (2003) conducted a cohort in Aortic root aneurysm (n=123). Preoperative aortic root diameter >60 mm or 50-60 mm vs. Preoperative aortic root diameter <50 mm was evaluated on 3-year survival (p=ns). Preoperative aortic root diameter had no significant impact on 3-year survival (98% for >60 mm, 96% for 50-60 mm, 100% for <50 mm; P=ns) after valve sparing aortic root reimplantation.
