    Intra Vascular Ultrasound (IVUS)
  2. What size sheath and guide catheter is used for IVUS?
    6-8 French
  3. During IVUS, what type of guide wire is passed to the distal part of the artery being examined?
    Angioplasty Guidewire (0.014)
  4. List six things that should appear on an IVUS image.
    • Adventia
    • Media

  5. What is the size of an IVUS catheter?
    • 2.9-3.5 French
    • Diameter (0.957-1.16mm)
  6. At the conclusion of an IVUS test, what is an angiography study being used to check for?
    Disruption or injury due to intravascular equipment on the coronary artery in question.
  7. How is IVUS used for Clinical Research?
    Restenosis prevention, proper stent placement, and proper stent expansion.
  8. One line blood flow, forward views of CTO, and HD imaging of better stable/unstable plaques are examples of the ________ of IVUS.
    Future Technological Developments
  9. What does FFR stand for?
    Fractional Flow Reserve
  10. Define FFR
    Translesional physiolocgical equipment used to determine if treatment is required
  11. What wire is similar to a standard 0.014 angioplasty guidewire, but has a transducer mounted on from it's tip?
    Pressure Wire
  12. Where is the transducer mounted on a pressure wire
    3cm from the tip
  13. What are the advantages of FFR?
    • Absolute value of 1.0
    • Not affected by hemodynamic perturbation
    • Specific for epicardial coronary disease
  14. What size guide catheter would a doctor normally choose for FFR?
    5 or 6 French
  15. What medications are normally administered preprocedure of FFR?
    Heparin and IC NTG
  16. If the doctor deems it neccesary, what can the pressure wire also be used for?
    Intervention
  17. What medication is adminstered to obtain maximum hyperemia in a FFR procedure?
    • Adenosine
    • (140 mcg/kg/min drip)
    • (20-30 mcg/kg/min IC)
  18. What type of stents are most commonly used in Peripherial vessels?
    Self expanding stents
  19. What are the self expanding stents made of?
    Nitinol
  20. List the periperhal vascular in order of blood flow.
    • Carotid Arteries
    • Subclavian
    • Renals
    • Abdominal Aorta
    • Iliac
    • Femoral
    • Popliteal (knees)
    • Anterior/Posterior Tibial
    • Dorsalies Pedis (top of foot)
  21. How do you determine FFR ratio?
    • Distal / Proximal
    • ex: 80/120 = 2/3 = 66%
  22. If FFR ratio is lower than _____% then a treatment (balloon or stent) will be needed.
    75%
