Coronary Angiogram

A minimally invasive diagnostic procedure to visualize the coronary arteries and identify blockages or narrowing that may be causing heart problems.

What is a Coronary Angiogram?

A coronary angiogram, also known as cardiac catheterization or coronary angiography, is a specialized X-ray imaging procedure used to examine the blood vessels of the heart. This diagnostic test allows Dr. Bleszynski to see inside your coronary arteries and identify any blockages, narrowing, or other abnormalities that may be affecting blood flow to your heart muscle.

During the procedure, a thin, flexible tube called a catheter is inserted through a blood vessel in your wrist (radial artery) or groin (femoral artery) and guided to your heart. A special contrast dye is then injected through the catheter, making your coronary arteries visible on X-ray images in real-time.

Who May Need a Coronary Angiogram?

Your doctor may recommend a coronary angiogram if you have:

Chest pain (angina) that doesn't respond to medication
Abnormal results from a stress test or other cardiac tests
Unexplained heart failure symptoms
Known coronary artery disease requiring assessment
Heart attack requiring urgent evaluation
Planned heart surgery or valve procedures
Congenital heart defects

What to Expect During the Procedure

Preparation

You'll receive a mild sedative to help you relax. The insertion site (wrist or groin) will be cleaned and numbed with local anesthesia.

Catheter Insertion

A small puncture is made, and the catheter is gently guided through your blood vessels to your heart using X-ray guidance.

Contrast Injection

Contrast dye is injected through the catheter. You may feel a warm sensation when the dye is released. Multiple images are captured from different angles.

Evaluation

Dr. Bleszynski reviews the images in real-time to assess your coronary arteries. If significant blockages are found, treatment may be performed during the same procedure.

Recovery & Aftercare

The procedure typically takes 30-60 minutes. Most patients go home the same day. Here's what to expect:

•You'll rest for 2-6 hours while the catheter site heals
•Drink plenty of fluids to help flush the contrast dye
•Avoid heavy lifting or strenuous activity for 24-48 hours
•You'll need someone to drive you home
•Most patients return to normal activities within 1-2 days

Frequently Asked Questions About Coronary Angiograms

Is a coronary angiogram painful?

Most patients experience minimal discomfort during a coronary angiogram. You will receive local anesthesia at the catheter insertion site (wrist or groin), so you should not feel pain during the procedure. You may feel some pressure when the catheter is inserted and a warm, flushing sensation when contrast dye is injected. Mild sedation helps you stay relaxed throughout.

How long does a coronary angiogram take?

The procedure itself typically takes 30-60 minutes. However, you should plan to be at the hospital for 4-6 hours total, including preparation time and recovery afterward. If a stent or other treatment is needed during the same procedure, it may take longer.

What are the risks of a coronary angiogram?

Coronary angiography is generally very safe. Rare risks include bleeding or bruising at the catheter site, allergic reaction to contrast dye, kidney problems from the dye (especially in patients with pre-existing kidney disease), heart attack, stroke, or arrhythmia. Serious complications are uncommon, occurring in less than 1% of procedures.

Can I eat before a coronary angiogram?

You will typically be asked not to eat or drink anything for 6-8 hours before the procedure. This is for your safety in case sedation is needed. You may take your regular medications with small sips of water unless your doctor advises otherwise. Be sure to inform your doctor about all medications, especially blood thinners.

Will I need someone to drive me home after the procedure?

Yes, you will need someone to drive you home after the procedure. The sedation used during the angiogram can affect your judgment and reflexes for several hours. You should not drive, operate machinery, or make important decisions for 24 hours after the procedure.
