Key result
In patients with bicuspid aortic stenosis, geometric deformation of self-expanding THVs at the inflow did not compromise immediate valve function, hemodynamics, or leaflet integrity.
Why the study?
Does geometric deformation of self-expanding transcatheter heart valves affect valve performance in patients with bicuspid aortic stenosis?

In bicuspid aortic stenosis, geometric deformation of self-expanding transcatheter heart valves at the inflow does not compromise immediate valve function, though calcified raphe is associated with increased paravalvular leak.
Becker et al. (2025) conducted an editorial in bicuspid aortic stenosis (n=175). Self-expanding Evolut THV was evaluated on Stent frame expansion and ellipticity and their relationship with valve performance. In patients with bicuspid aortic stenosis, geometric deformation of self-expanding THVs at the inflow did not compromise immediate valve function, hemodynamics, or leaflet integrity.
