iFR is in a class of its own

iFR is the leading hyperemia-free physiologic index for measuring pressure in diagnostic and interventional procedures. Only offered by Philips, iFR is an evidence-based methodology that improves outcomes, saves time, and reduces patient discomfort.1,2,3 iFR Co-registration maps the physiologic measurements, directly onto the angiogram enabling more complete procedural guidance.

iFR is recognized in key industry guidelines

 

  • Only iFR has been included in both the AUC (ACC Appropriate Use Criteria)4 and NCDR (National Cardiovascular Data Registry).5
  • Only iFR has been designated as “definitely beneficial” by SCAI (Society of Cardiac Angiography and Interventions).6
  • Only iFR has received a Class 1A ESC (European Society of Cardiology) guideline.7

Only iFR has clinically validated patient outcome data in the largest physiology studies ever

Proven outcomes

  • Validated in more than 4,500 patients1,2
  • Consistent outcomes as with FFR1,2
  • 0.89 cut-point backed by data1,2,8

Introducing Intrasight
Smart. Simple. Seamless.

Introducing the all-new Philips’ IntraSight applications platform where imaging, physiology, co-registration11 and software come together to facilitate optimal patient care. IntraSight offers a comprehensive suite of clinically proven modalities, such as, iFR/FFR, IVUS and co-registration11 to simplify complex interventions, speed routine procedures and provide improved patient care.

Only Philips has IntraSight with iFR Co-Registration for advanced physiologic guidance11

iFR co registration RCA length

iFR Co-registration maps iFR values directly onto the angiogram, allowing you to see precisely which parts of a vessel are causing ischemia.

  • Mapping of physiologic pressure drops onto the angiogram to better discern focal, serial or diffuse disease.
  • Precise lesion severity, location and length assessment.
  • Make length measurements without a cumbersome pull back device.
  • Physiologic impact of a virtual stent.
  • Plan your procedure with physiologic guidance.

Improving PCI with iFR Co-registration

Dr. Justin Davies explains how iFR co-registration can identify disease location and the likely impact of PCI before you stent

Transforming how we do PCI with iFR Co-registration

Dr. Allen Jeremias explains the need to understand not just whether there is ischemia, but where it is when planning for PCI
