Caas vFFR Identity
Sistema CAAS vFFR

The CAAS vFFR system is an innovative technology allowing for the non-invasive physiological assessment of coronary lesions without the need for pressure wires or hyperemic agents.

Introduction

CAAS vFFR calculates the pressure drop in coronary vessels without the need of a pressure wire. The vFFR module builds a 3D reconstruction of two angiograms and assesses pressure-drop, resulting in a vFFR value. Additionally, the 3D reconstruction will enable assessment of severity and percentage of stenosis.

Why?

  • No invasive pressure wire needed
  • No hyperemic agent needed
  • Easy, one-minute analysis
  • Pre- and post stenting analysis

Strengths

  • Only 2 angiograms needed
  • X-Ray system independent
  • Functional and anatomical measurements
  • 510(k) Cleared and CE Marked

“In the FAST II trial,” said Joost Daemen MD, PhD, principal investigator , “We confirmed that vFFR as calculated using CAAS vFFR has a high diagnostic accuracy to detect FFR ≤ 0.80 in an international multi-center setting. vFFR is an accurate, fast and easy to use tool to assess coronary physiology.”

High diagnostic accuracy and good correlation with invasive FFR

Broad clinical use

Optimize patient outcome using post stenting vFFR
assessment

  • Lower rate of MACE for the patient group with a post stenting
    vFFR value above 0.9 [5]

vFFR can be used for HeartTeam decision making.

  • vFFR might impact the way HeartTeam consensus is
    reached. As functional assessment of 3-vessel disease
    using vFFR is used in stead of anatomical assessment. [6]

vFFR can be used to predict the effect of the treatment
using the residual pressure drop and residual vFFR value.

Conclusion

The 3D-QCA derived vFFR has a high linear correlation to invasively measured FFR, a high diagnostic accuracy to detect lesions with an FFR ≤ 0.80 and a low interobserver variability.
