    Why It IsDone

    Frequent or severe chest pain(angina) that is not responding tomedication.Evidence of severely reduced blood

    flow (ischemia) to an area of heartmuscle caused by one or morenarrowed coronary arteries.An artery that is likely to be treated

    successfully with angioplastywhether or not stenting is also used.You are in good enough health toundergo the procedure

    STENTS

    A small, expandable wire tube is

    often permanently inserted into the

    artery during angioplasty.

    Balloon angioplasty

  • 7/31/2019 3011646 Angioplasty Vs

    11/33

    Stenting should:

    Open up the artery and press the

    plaque against the artery's walls,thereby improving blood flow.

    Keep the artery open after theballoon is deflated and removed.

    Seal any tears in the artery wall.

  • 7/31/2019 3011646 Angioplasty Vs

    12/33

    Prevent the artery wall fromcollapsing or closing off again(restenosis).

    Prevent small pieces of plaque frombreaking off, which might cause a

    heart attack.

    How Well It Works

    Angioplasty relieves chest pain

    and improves blood flow to theheart. If restenosis occurs,another angioplasty or bypasssurgery may be needed.

    RISKS:

    Bleeding at the puncture site.

    Sudden closure of the artery.Heart attack.

    Need for additional procedures. Angioplasty

    may increase the risk of needing urgent bypass

    surgery. In addition, the repaired artery can

    renarrow (restenosis) and a repeat angioplasty

    may need to be performed.

    Reclosure of the grafted blood vessel

    (restenosis).

    Death. The risk of death is higher when

    more than one artery is involved.

    How is coronary bypass done?

    Surgeons take a segment of a healthy blood

    vessel from another part of the body andmake a detour around the blocked part of the

    coronary artery.

    An artery may be detached from the chestwall and the open end attached to the

    coronary artery below the blocked area.

    29/33

    A piece of a long vein in your leg may be

    taken. One end is sewn onto the large arteryleaving your heart -- the aorta. The other end

    of the vein is attached or "grafted" to the

    coronary artery below the blocked area.

    Either way, blood can use this new path to flow

    freely to the heart muscle.
