Why the study?
Does transcatheter aortic valve implantation perform differently in patients with bicuspid aortic valve stenosis compared to those with tricuspid aortic valve stenosis?
Does transcatheter aortic valve implantation perform differently in patients with bicuspid aortic valve stenosis compared to those with tricuspid aortic valve stenosis?
TAVI in bicuspid aortic valves presents unique anatomical and procedural challenges, including larger annuli, more calcification, and valve-specific hemodynamic issues compared to tricuspid valves.
Alerts to anatomy-specific TAVI performance gaps in BAV; leaves open optimal valve selection pending dedicated trials.
In Preprocedural CT, patients with BAV have larger aortic annulus perimeters, and more calcified valves compared with TAV. In patients with BAV, self-expandable valves were under-expand and balloon-expandable valves have a trend toward increased rates of postimplantation AR grade. Self-expandable valves have higher postprocedural gradient in BAV compared with TAV.
