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.
7/31/2019 3011646 Angioplasty Vs
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.
