Transcatheter Aortic Valve Implantation (TAVI)

Cusp overlap technique

Driving consistency in your TAVI procedures

Precision

Facilitate implant depth accuracy
The cusp overlap technique isolates the noncoronary cusp (NCC) to provide an accurate anatomical view to assess and achieve the target implant depth.1

Control

Predictable valve deployment
Slow deployment starting at the supra-annular level allows the valve to descend to its target position with minimal catheter manipulation.

Optimize PRO interim clinical analysis1

Optimize PRO Study investigators use the cusp overlap technique and a prespecified conduction disturbance pathway, which contributes to excellent clinical outcomes, such as a single-digit pacemaker rate.*

  • 0 deaths or disabling strokes at 30 days
  • 0% moderate or severe PVL at discharge
  • 8.8% permanent pacemaker rate at 30 days
  • 8.1 mm Hg gradient at discharge
  • 1 day median length of stay

Predictable precision

Accurate depth assessment at the NCC, facilitated with the cusp overlap technique, has resulted in single-digit pacemaker rates in several single-center and multicenter clinical studies.

Single-digit new 30-day permanent pacemaker implantation rates

Bar chart highlighting 30-day pacemaker implant rates for multiple studies following TAVR or TAVI, depending on region or country

Excludes patients with baseline implantable cardioverter defibrillator or pacemaker.

TAVI risks may include, but are not limited to, death, stroke, damage to the arteries, bleeding, and need for permanent pacemaker.
