Description of the Procedure
During the procedure, you will receive IV fluids and medications. An EKG will be monitoring your heart's activity.
You will be awake but sedated so that you will be more relaxed. You will be asked to perform basic functions such as coughing, breathing out, and holding your breath. Tell your doctor if you feel any chest pain, lightheadedness, nausea, tingling, or other discomfort.
The catheter will be inserted into an artery in either the groin or arm.
The insertion area will be
cleaned, and numbed. A needle will be inserted into a blood vessel. A wire will be passed through the needle and into the blood vessel. The wire will then be guided through until it reaches your heart. A soft, flexible catheter tube will then be slipped over the wire and threaded up to your heart.
X-rays will be taken during the procedure to know where the wire and catheter are. Dye will be injected into the arteries of the heart. This will make the arteries and heart show up on the x-ray images. You may feel warm during the dye injection.

Once in place, the catheter can be used to take measurements. Blood pressure can be taken within the heart's different chambers. Blood samples may also be taken. Multiple x-ray images will be taken to look for any disease in the arteries. An aortogram may also be done at this time. This step will give a clear image of the aorta. After all the tests and images are complete, the catheter will be removed.
and stenting will be done if there is an area in your arteries that is narrow or clogged. These procedures help to open narrowed arteries.
Finally, a bandage will be placed over the groin or arm area.
How Much Will It Hurt?
Although the procedure is generally not painful, it can cause some discomfort, including:
- Burning sensation when the skin at the catheter insertion site is anesthetized
- Pressure when the catheter is inserted or replaced with other catheters
- A flushing feeling or nausea when the dye is injected
- Heart palpitations
Pain medication will be given when needed.
