Other interventions: Access site
The SAFER-TAVI trial is randomized study comparing secondary access via a transradial versus transfemoral approach among patients undergoing transfemoral TAVI for aortic valve disease. Secondary access is gained along with primary access at the commencement of the TAVI procedure and is used for aortography before and after valve deployment and for assessment of the primary femoral access site after closure to confirm haemostasis. For patients assigned to radial access, the radial sheath will be removed using a radial band at the end of the procedure. For patients assigned to femoral access, the puncture site will be obtained under ultrasound guidance and fluoroscopic landmark identification. Unless contraindicated, the use of vascular closure devices will be recommended for all femoral cases. The choice of closure device is at the discretion of the operator. Catheters used in the access groups will be 5 or 6 French size at the discretion of the operator.

Summary
Brief summary
Transcatheter aortic valve implantation (TAVI) is a well known safe treatment for severe
aortic stenosis. To perform TAVI safely, there is a need for two vascular entry (access)
sites: the primary and secondary access sites. While the femoral approach remains the most
common site for primary access, secondary access (which is needed for guidance during the
procedure) has drawn little attention in trials of TAVI. The two secondary access sites most
commonly used are the radial (through an artery in the wrist) and femoral (through an artery
in the groin) access sites. Observational studies comparing the two have shown a lower risk
of complications with radial access compared to femoral access, but there are no randomized
controlled data to confirm these findings. Accordingly, investigators aim to undertake a
multicenter, randomized controlled trial among patients who are undergoing transfemoral TAVI,
to assess if radial access is superior to femoral access as a secondary access site.
