The flashcards below were created by user pugluv01 on FreezingBlue Flashcards.

  1. coronary artery bypass graft (CABG)
    grafting of a portion of a blood vessel retrieved from another part of the body to bypass an occluded coronary artery, restoring circulation to myocardial tissue
  2. anatomosis
    opening; joining of two blood vessels to allow flow from one to the other
  3. endarterectomy
    incision and coring of the lining of an artery to clear a blockage caused by a clot or atherosclerotic plaque buildup
  4. transmyocardial revascularization (TMR)
    a laser technique used to open tiny channels in the heart muscle to restore blood flow
  5. valve replacement
    surgery to replace a diseased heart valve with an artificial one

    • Types of artificial valves:
    • - tissue: most commonly made from animal tissue such as porcine (pig) or bovine (cow)
    • - mechanical: made from synthetic material
  6. valvuloplasty
    repair of a heart valve
  7. endovascular surgery
    interventional procedures performed endoscopically at the time of cardiac catherization
  8. angioscopy
    use of a flexible fiberoptic angioscope accompanied by an irrigation system, a camera, a video recorder, and a monitor that is guided through a specific blood vessel to visually assess a lesion and select the mode of therapy
  9. atherectomy
    excision of atheromatous plaque from within an artery utilizing a device housed in a flexible catheter that selectively cuts away or pulverizes tissue buildup
  10. percutaneous transluminal coronary angioplasty (PTCA)
    a method of treating the narrowing of a coronary artery by inserting a specialized catheter with a balloon attachment, then inflating it to dilate and open the narrowed portion of the vessel and restore blood flow to the myocardium
  11. intravascular stent
    implantation of a device used to reinforce the wall of a vessel and ensure its patency (openness)
