The CAAS vFFR system is an innovative technology that enables the physiological evaluation of coronary lesions without pressure wires or hyperemic agents.
Strengths • Only 2 angiograms needed • X-Ray system independent • Functional and anatomical measurements • 510(k) Cleared and CE Marked 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.
- No invasive pressure wire needed
- No hyperemic agent needed
- Easy, one-minute analysis
- Pre- and post stenting analysis
- 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 
 Presented at TCT 2019
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. 
 Presented at TCT 2020
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.
