Cardiac Catheterization

Call (410) 897-0822

Your heart is in good hands at Luminis Health. Our skilled cardiac and vascular specialists diagnose, treat and manage a wide range of heart diseases. And cardiac catheterization is one of our specialties.

What Is Cardiac Catheterization?

Cardiac catheterization is a procedure that lets us see inside your heart's blood vessels using a hollow tube called a "catheter." We thread the catheter from an artery in your arm or groin to your heart.

Your doctor may order a cardiac catheterization if you have a cardiac condition or symptoms of heart disease. This procedure can:

  • Check how well your heart works.

  • Determine if you have blockages in any coronary (heart) arteries.

  • Evaluate how your heart's valves work.

  • Diagnose problems with your heart and figure out the best way to fix them.

If needed, we can perform life-saving procedures during cardiac catheterization. These include:

  • Angioplasty, in which we open a blocked artery with a tiny balloon.

  • Stenting, in which we insert a device to keep the artery open for longer.

Cardiac catheterization is a minimally invasive procedure. About 90% of the time, we use radial catheterization — the latest approach, in which the catheter goes into an artery in your arm. This method reduces your risk of bleeding and speeds up your recovery time.

Why Trust Luminis Health With Your Cardiac Catheterization?

We win awards for emergency heart attack care, but we've also prevented thousands of heart attacks with cardiac catheterization. You can trust us to manage coronary artery disease and keep you healthy with:

  • A dedicated heart center. Our Zazulia Heart and Vascular Center is an inpatient unit just for heart patients. It features cardiac catheterization labs, a critical care unit and a cardiac rehab center.

  • Heart treatments recognized by the American Heart Association. The American Heart Association recognizes us as one of only 25% of hospitals in the U.S. qualified to perform emergency cardiac catheterization.

  • Nationally recognized care. We're proud to appear on the 2022 U.S. News & World Report list of “Best Hospitals." The American College of Cardiology recognizes Luminis Health for our commitment to hospital care for heart patients.

What to Expect When You Get a Cardiac Catheterization

You shouldn't eat or drink anything before your procedure. Your doctor will give you any special instructions beforehand.

We perform cardiac catheterizations in a procedure room with special x-ray and imaging machines. While patients are typically awake, we'll give you medicine to relax you, so you might be a bit sleepy.


Your surgeon makes a small cut. It's usually in your arm, but in some cases we may need to insert the catheter into an artery in your groin instead. Next, we thread the catheter to your heart. The procedure itself takes about 30 minutes — although it could take longer if we discover you need cardiac angioplasty or a stent to treat blockages.

Immediately after your procedure, we monitor your incision site and vital signs. How long you stay in the hospital depends on your health and the reason for the cardiac catheterization, but it's possible you'll be able to go home the same day.


After the procedure, you'll feel sore for a few days and should take it slow. Most people are fully recovered from a cardiac catheterization within a week.
