CaFFR
New approach getting precision

CAFFR™
Innovative Delivery System
-
Get More Assurance
- No need to guess the state of hyperemia.
- To provide better correlation, top accuracy and faster calculation.
- To get more assurance to cardiologists.
-
Get More Guidance
- Monitoring real-time aortic pressure in all stages of cardiac cycle.
- Assessing more physiology parameters simultaneously to supply guidance for all diversified cases.
-
Get More Assurance
- No adenosine, guidewire required, wedging or drifting.
- Better connection and equilization
- CAFFR procedure can be fluently integrated in cath lab’s workflow.
- Easily deployed anywhere, FlashAngioTM will free up more operation from cardiologist.
-
Free Up Your Time
- Dedicated designed CFD algorithm offers resolution to Navier–Stokes formula in 30 seconds.
- No need to balance risk for applying FFR.
- With FlashAngioTM, FFR is always available whenever and wherever you want it, without time-consuming setup or connecting of cables.
A Milestone of FFR Analysis

Guided Procedures
-
1. Obtaining the 3D model of the blood vessels and calculating blood flow velocity based on angiographic image.
-
2. Using enhanced CFD approach to measure FFR value, get data in seconds.
-
3. Simplified live case documentation with vessel 1 and procedure step annotation.
FAME
- Allows more accurate identification of hemodynamically relevant stenosis.(1)
- Reduces mortality and myocardial infarction by 34% at two years.(2)
- Reduces the amount of contrast media used and lower the general cost.(3)
- Improves outcomes and patient quality of life.(4)
- No increase in procedure time.
FAME Ⅱ
- The MACE happened to FFR-guided PCI group were significantly lower than the medical therapy group.(3)(4)
- 86% relative reduction in the risk for ACS requiring unplanned hospital readmission with urgent revascularization.
- Greater relief of angina.
- Cost-effectiveness-ICER of $32,000 per QALY

Study Result
- Patients with moderate stenosis (50-70% Stenosis) .1/3 of them will be ignored by angiography alone.
- Patients with severe stenosis (>70% Stenosis). 20% of them will be over treated by angiography alone.
Supported By Guidelines
- FFR was awarded the highest level of evidence, Class I, level of Evidence a, by the European society of Cardiology (ESC) and the European association for Cardio-thoracic surgery (EACTS).(5)
- The ACC/AHA/SCAI guidelines are Class II a, level of Evidence a, for determining whether PCI of a specific coronary lesion is warranted.(6)

More than FFR
Unique multi-functionality with proprietary sensor chip technology enables assessment of multiple parameters with FlashPressureTM, the real-time measure sensor capable of simultaneous assessment of FFR, CFR and IMR and cFFR in all sector of one cyble Pd/Pa.


Superior Accuracy of CAFFRTM
FlashAngioTM demonstrated best correlation to FFR measurement in lately cliniDuring standardized testing, FlashAngioTM running time is within 30s, and get the results(8)
91% for FFR values between 0.75-0.85. The sensitivity and specificity were 92% and 98%, respectively.
