CARDIAC CATHETERIZATION

Cardiac catheterization

How the Test is Performed

You will get medicine before the test to help you relax.

The health care provider will clean a site on your arm, neck, or groin and insert a line into one of your veins. This is called an intravenous (IV) line.

A larger thin plastic tube called a sheath is placed into a vein or artery in your leg or arm. Then longer plastic tubes called catheters are carefully moved up into the heart using live x-rays as a guide. Then the doctor can:

  • Collect blood samples from the heart
  • Measure pressure and blood flow in the heart's chambers and in the large arteries around the heart
  • Measure the oxygen in different parts of your heart
  • Examine the arteries of the heart
  • Perform a biopsy on the heart muscle
  • For some procedures, you may be injected with a dye that helps your doctor to visualize the structures and vessels within the heart. 

If you have a blockage, you may have angioplasty and a stent placed during the procedure.

The test may last 30 - 60 minutes. If you also need special procedures, the test may take longer. If the catheter is placed in your groin, you will often be asked to lie flat on your back for a few to several hours after the test to avoid bleeding.

You will be told how to take care of yourself when you go home after the procedure is done.
