Coronary stenting is a way to open a blocked artery in the heart. During an angioplasty, a mesh, metal tube is placed in the artery. The tube is called a stent.
There are 2 types:
Reasons for Procedure TOP
Coronary stenting allows for better blood flow to feed the heart muscle. It may mean that you will no longer have chest pain. Activities may become easier.
Possible Complications TOP
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review possible problems such as:
Sometimes the stent isn’t enough or the artery narrows again. This may result in another procedure.

What to Expect TOP
Prior to Procedure
You may have:
Leading up to your procedure:
The insertion site is numbed with a local anesthetic. A mild sedative given ahead of time will help you relax.
Description of Procedure TOP
The catheter is placed into an artery in either the groin or arm. The area will be cleaned and numbed. A needle is placed into a blood vessel. A wire is passed through the needle and into the blood vessel. The wire is then threaded to the block. A soft, flexible tube is slipped over the wire and threaded up to this point.
X-rays help to know where the wire and catheter are. Dye is injected into the arteries of the heart. This makes the block easier to see. You may feel warm when the dye is injected.
There’s a small balloon at the tip of the catheter. It will be quickly inflated and deflated. This will stretch the blocked artery open.
The flattened stent will be placed. The balloon is reinflated to open the stent to its full size. The stent will remain in place to hold the vessel walls open. The balloon, catheter, and wire will be removed.
The insertion site is covered with a bandage.
Immediately After Procedure TOP
You will need to lie still and flat on your back for a period of time. Pressure on the site will control bleeding.
