NCT03520101
Comparison of the Balloon-Expandable Edwards Valve and Self-Expandable CoreValve Evolut R or Evolut PRO System for the Treatment of Small, Severely Dysfunctional Surgical Aortic Bioprotheses. The 'LYTEN' Trial
The treatment with transcatheter aortic valve implantation (TAVI) of patients with small (≤23mm) surgical bioprostheses remains a challenge due to the increased transvalvular residual gradients and high rates of severe prosthesis-patient mismatch (PPM) following the procedure.

NCT05714293
CT-evaluation of Coronary Ostia Height After Surgical Aortic Valve Replacement.
The goal of this interventional, single-center study is to demonstrate if there is a change in the coronary ostia height after surgical aortic valve replacement and if it depends on the type of prosthesis or surgical technique used. The study involves patients undergoing elective surgical aortic valve replacement with a bioprosthesis. Participants enrolled will undergo a CT scan before and after surgery (at least 90 days after surgery) to analyze coronary ostia height.
