Radial versus femoral secondary access during TAVI

Radial Versus Femoral Secondary Access in Patients Undergoing TAVI

NA · University Heart Center Freiburg - Bad Krozingen · NCT07399392

This trial tests whether using the wrist (radial) artery instead of the groin (femoral) artery for the small secondary access during transfemoral TAVI lowers vascular complications in adults with severe aortic stenosis.

What this trial studies

Patients scheduled for transfemoral TAVI will receive the standard large femoral access for the valve and a second smaller access for the pigtail catheter either via the radial (wrist) artery or the femoral (groin) artery. The study compares vascular complications, bleeding events, and short-term procedural outcomes between the two secondary access approaches. Eligible adults (18+) who can give informed consent and have accessible radial and femoral arteries are included, while those with inaccessible access sites, hostile anatomy, or hemodynamic instability are excluded. The trial is carried out at the University Heart Center Freiburg using routine TAVI care with the alternative secondary access implemented per protocol.

Who should consider this trial

Good fit: Adults (18+) scheduled for transfemoral TAVI who can give informed consent and have suitable radial and femoral arteries are ideal candidates.

Not a fit: Patients with non-accessible radial or femoral arteries, hostile transfemoral anatomy, hemodynamic instability, or lack of capacity to consent are unlikely to benefit from this approach.

Why it matters

Potential benefit: If successful, using radial secondary access could reduce vascular complications, bleeding, and recovery time after transfemoral TAVI.

How similar studies have performed: Observational studies and registry data have suggested radial secondary access may lower vascular complications compared with femoral access, but large randomized evidence is limited.
