The novel angio-based functional lesion assessment: wire and adenosine free

Copy of Untitled Design (11).png
Key product features

  • Angiographically derived pressure drop and vFFR value

  • Fits seamlessly in normal cathlab workflow using just 2 contrast filled angiograms

  • Vendor independent: compatible with most X-ray systems

Functional lesion information

  • Pressure drops in coronary artery

  • vFFR value

Anatomical lesion information

  • Lesion diameter

  • Percentage stenosis

  • Reference diameter

  • Obstruction length

Pressure drop in the coronary arteries

The vFFR workflow builds a 3D reconstruction of coronary artery and assesses pressure drop, resulting in a vFFR value. Furthermore, the 3D reconstruction enables assessment of severity and percentage of stenosis.

Clinical Trial Data

  • vFFR is subject of two multi-center randomized clinical trials investigating the effectiveness of vFFR guided revascularization vs FFR guided revascularization in over 4000 patients:

    • The FASTIII trial is led by Dr. Joost Daemen (Erasmus Medical Center, Rotterdam, The Netherlands) , investigator initiated and sponsored by the European Cardiovascular Research Institute (ECRI). All study details can be found here: https://www.ecri-trials.com/studies/fast-iii/

    • The LIPSIA STRATEGY trial is led by Prof. Holger Thiele (Herzzentrum Leipzig) and investigator initiated. More information can be found here: https://www.clinicaltrials.gov/ct2/show/NCT03497637   

  • vFFR is and has been subject to multiple single and multi-center trials investigating diagnostic accuracy to predict FFR ≤ 0.8, accuracy in post-PCI setting and accuracy related to IVUS, OCT, NHPR. A full overview can be found here.
