NCT06049654
Comparison of Allegra vs Sapien Transcatheter Aortic Valves in Valve-In-Valve Indication
The VIVALL-2 study is a randomized trial to compare the self-expandable supra-annular Allegra and the balloon-expandable intra-annular Edwards transcatheter valve systems in patients with degenerated biological aortic surgical valve.

The ReTAVI Prospective Observational Registry
Patients with severe aortic stenosis (sAS) treated with transcatheter aortic valve implantation (TAVI) (increasingly younger \& lower risk pts) are experiencing SVD of the index THV and thus developing an indication for a redo-TAVI procedure. The evidence on redo-TAVI (where a transcatheter heart valve \[THV\] is implanted into another THV) is limited, with initial data showing acceptable safety as well efficacy in highly selected and limited populations. Aim is to evaluate short- and long-term data on patients undergoing transcatheter redo-TAVI procedures with THVs for failure of a previously implanted THV and to determine VARC-3 defined efficacy and safety at 30 days and functional outcome at 1 year, 3 years and 5 years.
