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: A Pilot Prospective Randomized Trial. The 'LYTEN' Trial

Brief summary (registry, in English)

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.
