Key result
A modified Ross procedure with reduction annuloplasty and Dacron graft replacement decreased ascending aorta diameter from 42 mm preoperatively to 25 mm early after surgery (p<0.001).
Why the study?
Does a modified Ross procedure with reduction annuloplasty and Dacron graft replacement prevent late autograft dilatation in patients with bicuspid aortic valve and ascending aorta dilatation?
Population
31 adult and paediatric patients with bicuspid aortic valve and dilatation of the ascending aorta
Design
Cohort
Follow-up
mean 2.5+/-2.2 years (range 3 months to 8 years)

May support modified Ross with annuloplasty and grafting for early aortic reduction in BAV; leaves open late autograft durability and RCT confirmation.

A modified Ross procedure combining reduction annuloplasty and Dacron graft replacement of the ascending aorta effectively prevents early- to mid-term autograft dilatation in patients with bicuspid aortic valves.
Brown et al. (2010) conducted a cohort in Bicuspid aortic valve and dilatation of the ascending aorta (n=31). Modified Ross procedure with reduction annuloplasty and Dacron graft replacement vs. Preoperative baseline was evaluated on Diameter of the ascending aorta (p=<0.001). A modified Ross procedure with reduction annuloplasty and Dacron graft replacement decreased ascending aorta diameter from 42 mm preoperatively to 25 mm early after surgery (p<0.001).
