Video: Coronary angioplasty – Mayo Clinic

Percutaneous coronary intervention, also acknowledged as coronary angioplasty, opens narrowed coronary arteries.

In this course of action, doctors insert a long, thin tube called a catheter in an artery in the groin or wrist and thread it to the impacted artery working with X-ray imaging. Medical professionals then inject a smaller total of dye by means of the catheter to the artery to aid them see any blockages or narrowing on X-ray images. A catheter with a balloon on the tip is then inserted by means of the first catheter and guided to the heart.

When the catheter reaches the narrowed or blocked location of the artery in the heart, doctors inflate the balloon to reopen the artery and enhance blood circulation. The balloon is then deflated and taken off.

In most instances, doctors then insert a different catheter with a mesh tube hooked up called a stent. The stent is then positioned in the narrowed location of the artery to avoid re-narrowing just after the artery is widened. Medical professionals then remove the catheter.
