The Ross operation — a feasible and safe option in the setting of a bicuspid aortic valve?
Why the study?
Does the presence of a bicuspid aortic valve affect autograft function and root diameters over time after the Ross operation compared to a tricuspid aortic valve?

Implication
Supports Ross feasibility in BAV without excess regurgitation; leaves open long-term dilatation effects.
Structured PICO
Does the presence of a bicuspid aortic valve affect autograft function and root diameters over time after the Ross operation compared to a tricuspid aortic valve?
P
Population
1,277 patients (mean age 42.2 ± 15.3 years) undergoing the Ross operation with intra-operatively documented aortic valve morphology (bicuspid or tricuspid) from the German Ross Registry.
I
Intervention
Ross operation in the setting of a bicuspid aortic valve (BAV)
C
Comparator
Ross operation in the setting of a tricuspid aortic valve (TAV)
O
Outcome
Autograft function (neo-aortic regurgitation) and diameters (annulus, sinus, sinotubular junction) over timesurrogate
The Ross operation in patients with a bicuspid aortic valve is feasible and does not lead to increased neo-aortic regurgitation over time compared to tricuspid valves, despite slightly higher rates of root dilatation.
