Fractional Flow Reserve (FFR) Definition of FFR: “Maximum achievable blood flow in stenotic coronary artery divided by Maximum blood flow in the same artery without stenosis”
FFR Measurement Correlates to the Likelihood of Ischemia Fractional Flow Reserve (FFR) is a lesion specific, physiological index determining the hemodynamic severity of intracoronary lesions. FFR accurately identifies lesions responsible for ischemia which in many cases would have been undetected or not correctly assessed by angiography or IVUS. FFR Measurement Correlates to the Likelihood of Ischemia with a validated cut off value of 0.75.
The FAME Study The FAME (Fractional Flow Reserve vs. Angiography for Multivessel Evaluation)Study one-year results, published in The New England Journal of Medicine, shows that routine measurement of FFR in patients with complex coronary artery disease reduces MACE and makes stent placement more efficient and more cost-effective. In the FAME Study, 1005 patients with multivessel CAD were randomly assigned to FFR-guided PCI or angiography-guided PCI with DES and followed for one year.
FAME Study Design Chart Patient with lesions ≥ 50% in at least 2 of the 3 major epicardial vessels Indicate all lesions ≥ 50% amenable for stenting Randomization FFR-guided PCI Angiography-guided PCI Measure FFR in all arteries with ≥ 1 stenosis Stent only those stenoses with FFR ≤ 0.80 Stent all indicated stenoses 1-year follow-up Exclusion criteria: LM disease, Previous CABG MI < 5 days, unless Cardiogenic shock Pregnancy, Life expectancy < 2 years
Compared to angiography-only procedures, FAME one-year results show that FFR: Reduces MACE at one year by 28%. Reduces mortality and myocardial infarction at one year by 34%. Is cost saving and does not prolong procedure time. Decreases amount of contrast agent used. Results in similar, if not better, functional status. FAME two-year results show that FFR: Reduces mortality and myocardial infarction (combined) by 34%. Reduces myocardial infarction alone by 37%. Is cost saving and improves procedure outcomes. Save on average $2066 over one year. The FAME Study Results

Hydrophilic Coating The hydrophilic coating on PressureWireCertus Generation 7 has been found to significantly reduce friction in bench test models as compared to the non-hydrophilic Volcano Primewire Slydx. Vessel friction evaluated in bench model. The force required to pull each wire through a vessel fixture was measured. Data on file.
Hydrophobic connector Hydrophobic connector Hydrophobic Connector • The protective hydrophobic connector on PressureWireCertus is designed to: • Repel blood and fluids • Prevent leakage currents • Reduce the risk of signal problems
Hydrophobic Connector The hydrophobic connector on PressureWireCertus has been found to significantly reduce reconnection problems in wet conditions as compared to the non-hydrophobic connector on Volcano Primewire. * Re-connection of PressureWire Certus compared to Volcano Primewire after equal disconnection time in a wet condition to simulate actual use (measured in seconds). Data on file.
Large entry funnel Proximal Connector • The unique ergonomically designed proximal female connector on PressureWireCertus is designed • For fast and easy wire reconnection. • Reduce wire insertion friction • With an easier to use on/off locking mechanism
