Why the study?
Does transcatheter aortic valve implantation improve survival compared to surgical aortic valve replacement in intermediate and high-risk patients with severe aortic stenosis?

TAVI provides a significant survival benefit over SAVR at 2 years in intermediate and high-risk patients with severe aortic stenosis, especially via the transfemoral approach and in females.

Supports TAVI preference over SAVR in intermediate/high-risk severe AS; reinforces randomized evidence for transfemoral access and females.
