Video: Coronary angioplasty – Mayo Clinic

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

In this technique, medical professionals insert a prolonged, skinny tube termed a catheter in an artery in the groin or wrist and thread it to the influenced artery utilizing X-ray imaging. Medical doctors then inject a compact sum of dye by the catheter to the artery to help them see any blockages or narrowing on X-ray photos. A catheter with a balloon on the tip is then inserted by means of the very first catheter and guided to the heart.

When the catheter reaches the narrowed or blocked area of the artery in the heart, medical practitioners inflate the balloon to reopen the artery and boost blood circulation. The balloon is then deflated and removed.

In most circumstances, medical doctors then insert one more catheter with a mesh tube attached called a stent. The stent is then positioned in the narrowed location of the artery to stop re-narrowing after the artery is widened. Physicians then take away the catheter.
