QFR® (Quantitative Flow Ratio)
QFR® is the innovative technology allowing for the non-invasive assessment of functional significant coronary lesions, without the use of adenosine or pressure wires. In addition detailed anatomical information is obtained that assists the healthcare professional in treatment decisions.

Benefits

The novel and patented QFR® approach applies advanced mathematical modelling to accurately and effectively measure the physiologic and anatomical extent of a patient’s coronary artery disease. QFR® also improves the patient experience with fast procedure times, no invasive devices or adenosine administration is required.

General Benefits

  • Proven accuracy

QFR® is proven to have good correlation and agreement with FFR,
by 12.000+ patients and 15.000+ lesions in 110+ peer reviewed articles.

  • Time & Cost Efficiency

No pressure wire, no adenosine, reduces treatment costs and procedure time

  • User Friendly

Simpler Intuitive workflow, applicable for online and offline usage

Clinical Benefits

  • QFR® can be used for the assessment of the result post-PCI , thereby facilitating quality control
  • QFR® allows assessment of non-culprit lesions to decide on Yes or No staged procedure, potentially saving the second intervention procedure

QFR® features

Image Acquisition

Simpler, Faster, Wireless Coronary Physiology – QFR 2.1

  • Automated Frame Counting for easier QFR analysis
  • Improved Contour Detection especially on low dose images
  • Improved Image export

Image Analysis

Automatic ED frame selection based on ECG

QFR® provides 2 different flow models:

  • Fixed flow QFR®, using fixed flow velocity
  • Contrast QFR® based on the contrast frame count

QFR® Results

  • 3D anatomic info for stent sizing
  • Allows prioritization of serial lesions
  • Residual QFR® predicts the effect of an intervention on the resulting QFR® value
  • User Lesion: Lesions can be combined by adding user lesion, so the lesions can be compared for optimal treatment planning
