Introducing the

iFR Scout
pullback technology

How iFR Scout works

iFR Scout pullback technology reveals the physiologic profile of the entire vessel, so when you encounter diffuse disease or serial lesions you can make informed treatment decisions.
ifr-scout-angio
This angio shows both focal and diffuse disease.
Which areas are the most physiologically significant?
ifr-scout-screen
The iFR Scout pullback shows the most significant gradient in the mid-vessel lesion with diffuse proximal disease.

Make the shift from justification to guidance

ifr-scout-in-use
Physiology is more than a justification tool. Hyperemia-free iFR Scout pullback technology makes it easier to assess physiology before, during and after your procedure.

iFR Scout pullback pre-intervention

ifr-scout-pre-intervention
The physician chose to treat the distal two focal lesions with two drug eluting stents.

iFR Scout pullback post-intervention

ifr-scout-post-intervention
The iFR Scout pullback demonstrates a functional gain from 0.85 to 0.92.

iFR Scout key new features

 

  1. iFR Scout pullback assessment reveals the physiologic profile of the entire vessel
  2. Live iFR and Pd/Pa measurements provide real-time physiologic assessment
  3. Highlighted wave-free period shows where the iFR measurement is being calculated

Benefits of iFR Scout pullback technology

check
No hyperemic agent required
check
Simple graphical display of iFR values through the vessel
check
Maps the ischemic contribution of each lesion without the confounding effects observed with FFR pullback 1
check
Easily bookmark areas of interest

Limitations of FFR pullback

cross
Requires IV hyperemia
cross
Can be difficult to interpret
cross
There is an interdependency of pressure gradients in serial lesions 1
cross
Requires a second FFR pullback after treating the first lesion to assess the “updated” severities of the remaining lesions

Untethered steering – from tip to clip

 

Experience the freedom of untethered steering from tip to clip.2 Many factors impact wire performance including tip design, wire support, and torque response. Fundamental to guide wire handling is the ability to maneuver the wire untethered. The Verrata Pressure Guide Wire quickly disconnects and reliably reconnects, freeing physicians to steer like a frontline wire.

iFR modality

Simplifies workflow

 

iFR modality simplifies workflow by providing a hyperemia-free measurement to assess lesion significance in as few as five heartbeats. Philips Volcano’s proprietary iFR modality has a robust body of clinical evidence with over 4,000 patients in numerous studies and peer-reviewed journal articles; evidence proves iFR of 0.89 is equivalent to an FFR of 0.80.3
