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

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

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

Simpler Intuitive workflow, applicable for online and offline usage

Clinical Benefits

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
