Hearing that you need a procedure on your heart can be an intimidating experience. If your cardiologist has recommended a cardiac catheterization, you likely have many questions about what the procedure entails, how it feels, and what the recovery process looks like. Fortunately, cardiac catheterization is one of the most common, safe, and effective diagnostic procedures performed in modern cardiology. This comprehensive guide will walk you through exactly what to expect, helping you feel prepared and confident.
Cardiac catheterization is a minimally invasive procedure used to diagnose and treat a variety of cardiovascular conditions. The term "catheterization" refers to the use of a catheter, which is a long, thin, flexible tube.
During the procedure, a specialized cardiologist (an interventional cardiologist) inserts this catheter into a blood vessel, usually in your wrist or your groin. Using advanced X-ray imaging as a guide, the doctor carefully threads the catheter through your blood vessels until it reaches your heart. Because there are no nerve endings inside your blood vessels, you do not feel the catheter moving through your body.
Once the catheter is in place, your doctor can perform several different tests or treatments depending on your specific needs.
Cardiologists use this procedure to gather precise, detailed information about how well your heart is functioning. Your doctor may recommend a cardiac catheterization to:
In many cases, if a blockage is found during the diagnostic portion of the procedure, your doctor can treat it immediately during the same session. This is done by performing an angioplasty (using a tiny balloon to open the artery) and placing a stent (a small wire mesh tube) to keep the artery propped open.
Proper preparation is essential for a smooth and safe procedure. Your healthcare team will give you specific instructions, but general guidelines usually include:
The procedure is performed in a specialized hospital room called a cardiac catheterization laboratory, or "cath lab." The entire process usually takes about an hour, though it may take longer if an angioplasty or stenting is performed.
You will change into a hospital gown and lie on an X-ray table. A nurse will start an intravenous (IV) line in your arm to deliver fluids and a mild sedative. You will remain awake and able to follow instructions, but you will feel very relaxed and slightly drowsy.
The insertion site (either your wrist or your groin) will be cleaned, shaved, and numbed with a local anesthetic. You will feel a brief sting from the numbing medication, but after that, you should only feel a sensation of pressure as the catheter is inserted.
If your doctor performs an angiogram, you may feel a sudden, warm flush spread through your body or a metallic taste in your mouth when the contrast dye is injected. This is completely normal and passes within a few seconds.
Once the procedure is complete, the catheter is removed. If the insertion site was in your groin, the doctor or nurse will apply firm pressure to the area for 10 to 20 minutes to stop the bleeding, or they may use a small closure device. You will then need to lie completely flat and keep your leg straight for two to six hours.
If the insertion site was in your wrist, a special pressure band will be placed around your wrist. You will be able to sit up and walk around much sooner, which is why the wrist approach is becoming increasingly popular.
Most patients go home the same day, though you may need to stay overnight if you had a stent placed or if you require further observation. For the first few days at home, you should avoid heavy lifting, strenuous exercise, and straining. You may notice a small bruise or a small, pea-sized lump at the insertion site, which is normal and will fade over time.
