  1. What is coronary baloon angioplasty?
    Catheter placed down to lesion in coronary artery and baloon inflated to reduce narrowing
  2. What is the chance for restenosis?
    40% roughly
  3. General indications for PCI?
    • - Stable ungina with aid of Positive ETT
    • - Unstable angina
    • - Acute MI
    • - After MI
    • - Following CABG
  4. What is AHA classification for Class I PCI?
    Conditions indicating that procedure/treatment will be useful and effective
  5. What is AHA classification for Class III PCI?
    Evidence suggests procedure/treatment is not useful and may cause harm
  6. Why use a guide catheter instead of a diagnostic catheter?
    • - Larger lumen for baloons and stents
    • - Radio-opaue tip
    • - Reinforced tip with a mesh support
  7. Why might an "over the wire" balloon be used instead of a "monorail" balloon?
    • - Used in chronic total occlusions
    • - Provides greater strength for crossing the lesion
  8. Name one con about "over the wire" balloons
    May lose guidewire when pulling the balloon out, resulting in loss of access
  9. How is monorail ballooning formed?
    Guide wire passes through the balloon itself, exiting the catheter proximal to the balloon
  10. What are the two types of stent?
    Bare metal stent and drug eluting stent
  11. What does a DES do?
    Inhibits cell growth, allowing vessle to maintain its patency
  12. Who are considered for DES?
    • Vessel <3mm in diameter
    • Lesion >15mm
    • Diabetic
    • Increased risk of stenosis
  13. Name 2 DES drugs:
    • Cypher (Sirolimus)
    • Taxus (Taxol)
    • Dexamet (Dexamethsone)
    • Janus Carbostent (Tacrolimus)
  14. When would restenosis occur post PCI?
