Brainiac Breakdown

The buildup of plaque in an artery wall of the heart, blocking the flow of blood could cause you to undergo a coronary angioplasty procedure. The steps of the procedure, done to improve the blood flow in an artery, are depicted.

00:00A coronary angioplasty procedure is also known as percutaneous coronary intervention.

00:11The procedure is done on blood vessels called coronary arteries.

00:16They supply your heart muscle with oxygen.

00:21The goal is to restore blood flow if a substance called plaque has significantly narrowed these

00:27vessels.

00:30To begin the procedure, the doctor will numb the skin in your wrist.

00:35A needle will be placed through your skin and into your radial artery.

00:39Next, a flexible guide wire will be passed through the needle into your artery.

00:45Then the needle will be withdrawn.

00:48It will be exchanged for a small, flexible tube called a sheath.

00:53This permits access into your artery.

00:56You may feel pressure when the doctor inserts the sheath, but you will not feel it moving

01:01inside your artery.

01:03Next, the guide wire will be advanced up to your heart.

01:09A flexible tube called a catheter will be advanced over the wire to your coronary arteries.

01:16The progress of the procedure will be checked with an x-ray device called a fluoroscope.

01:21At this point, your doctor will remove the guide wire.

01:24Then, the doctor will move the tip of the catheter just inside the coronary artery to be examined.

01:31A special dye will be injected into the artery.

01:35This allows your doctor to view it better with a fluoroscope.

01:38The dye will make any blockages in the artery stand out.

01:43If a significant blockage is found, your doctor will insert a guide wire into the artery.

01:49A balloon on the tip of the catheter will be moved along the wire to the blockage.

01:55When the balloon inflates, it will expand the artery and improve the blood flow.

02:01You may feel some chest discomfort while this is happening.

02:05After this, your doctor will deflate and remove the balloon.

02:13A wire mesh tube called a stent may be placed in the treated area.

02:17The stent helps keep the coronary artery open.

02:21Another doctor will choose the proper size stent, which is compressed over a balloon.

02:28The stent will be moved into the artery over the same guide wire.

02:31When the balloon is inflated, the stent will expand and lock into place.

02:38After the balloon catheter is taken out, the stent will stay in place to hold the artery

02:42open.

02:45At the end of the procedure, the guide wire will be removed.

02:49To find out more about coronary artery angioplasty, talk to your health care provider.
