Cardiac Catheterization

What is cardiac catheterization?

Cardiac catheterization is a diagnostic procedure that assesses how well your heart works. During the process, your board-certified cardiologist measures blood flow and blood pressure as it moves through your heart. 

Your doctor may administer a contrast dye during the procedure to perform a cardiac angiography, which finds blockage in your arteries. 

Who needs a cardiac catheterization?

Your primary care provider or cardiologist at Cardiology Specialists of Orange County explains why you may benefit from a cardiac catheterization. 

They may recommend this diagnostic test to:

• Look for blockages or narrowing in your cardiac arteries
• Assess pressure and oxygen levels in your heart
• Evaluate pumping in the chambers of your heart
• Diagnose cardiac abnormalities
• Check the structure and function of your heart valves
• Take a biopsy of your cardiac tissue

Your cardiologist may also perform other procedures during your cardiac catheterization, such as angioplasty and stent placement.

How do I prepare for a cardiac catheterization?

Your provider at Cardiology Specialists of Orange County gives specific instructions on how to prepare for your cardiac catheterization. Your doctor may request that you not eat or drink at least six hours before your test.

You may also need to modify your usual medication schedule. 

What happens during a cardiac catheterization?

The team at Cardiology Specialists of Orange County performs your cardiac catheterization in a cardiac cath lab. Before starting the procedure, your provider administers a sedative through an intravenous line in your arm to help you relax. You remain awake during the process. 

Your cardiologist inserts a special catheter through a small puncture in an artery. Using X-ray guided imaging, your provider slowly advances the catheter towards your heart. You’re given a local anesthetic before catheterization to minimize discomfort. 

Your doctor then measures, evaluates, and treats your heart issue using special instruments attached to the catheter. The entire procedure takes about an hour.

What happens after cardiac catheterization?

After your cardiac catheterization, your doctor sends you to the recovery area for monitoring. Your cardiologist may send you home the same day or admit you to the hospital for continued monitoring and care. 

Your provider at Cardiology Specialists of Orange County reviews your cardiac catheterization findings with you and provides additional recommendations.
