On the day of your operation, you will be asked to put on a surgical gown. You may receive a sedative by mouth and an intravenous line may be put in. You will then be transferred to the operating table. To begin, your leg and groin are swabbed with an antiseptic solution. Then the doctor will make a small cut over the femoral artery in the upper part of the leg.

A special needle is then inserted into the artery itself. Then a guide wire is carefully passed through the needle and gently pushed into the artery and upwards towards your chest. A narrow tube, called a catheter is threaded along the wire until it too has reached the coronary artery. Next, the doctor uses the catheter to inject a dye into the artery itself. The die shows up on a TV monitor and is used to pinpoint the exact location of the blocked area. Once the restricted area has been identified, a thin wire is inserted into the catheter, and is guided all the way to the blocked area and then slightly beyond. This wire acts as guide for the balloon catheter.

It allows your doctor to position the deflated balloon precisely in the middle of the narrowest part of the coronary artery. The balloon is briefly inflated. As it expands, it squeezes the plaque deposits against the wall of the artery. It also stretches the artery wall and enlarges the channel through which blood flows.

Your doctor will continue to inflate and deflate the balloon until normal blood flow has been restored. The balloon catheter is then withdrawn and another balloon catheter is inserted. This balloon has the mesh stent tube wrapped around it. Once this tube has been placed in the center of now widened area of the artery, the balloon is briefly inflated.

The stent expands until it hugs the walls of the artery. Finally, after a thorough investigation of the region, the catheters and guide wire are withdrawn and the stent remains permanently to provide support to the artery and to resist the buildup of plaque. The dye that had been injected will break up and leave your body as waste.

Slight pressure is applied to the incision in your leg in order to prevent bleeding.
