|
Angioplasty
|
a balloon catheter is passed through the guiding catheter to the area near the narrowing. A guide wire inside the balloon catheter is then advanced through the artery until the tip is beyond the narrowing.
•the angioplasty catheter is moved over the guide wire until the balloon is within the narrowed segment. •balloon is inflated, compressing the plaque against the artery wall •once plaque has been compressed and the artery has been sufficiently opened, the balloon catheter will be deflated and removed |
