Video: Coronary angioplasty

By Mayo Clinic staff

Transcript

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

A catheter inserted in an artery in the groin or arm is threaded to the affected artery. A second catheter is then inserted inside the first one.

When the catheter reaches the narrowed area, a balloon on its tip is inflated to reopen the artery.

While the catheters are in the artery, a stent may be placed to prevent re-narrowing after an artery is widened.
