Angiography / Cardiac Cath

Angiography, also known as Cardiac Catheterization, is a minimally invasive procedure used to diagnose heart conditions. It provides detailed images of the heart's blood vessels, helping doctors detect blockages or narrowing.

How Cardiac Catheterization Works

During the procedure, a thin, flexible tube called a catheter is inserted into a blood vessel—usually in the groin, arm, or wrist. This tube is guided toward the heart using X-ray imaging.

Once it reaches the heart, a contrast dye is injected. The dye makes the coronary arteries visible on an X-ray screen, revealing any blockages, plaque buildup, or structural issues.

When Is Angiography Needed?

• You have chest pain or angina
• You experience shortness of breath
• You show abnormal ECG or stress test results
• There's a suspected heart valve issue
• You're being evaluated before heart surgery

Early diagnosis can prevent life-threatening complications.

Types of Cardiac Catheterization

• Coronary Angiography: This is the most common type. It evaluates the coronary arteries for blockages or narrowing.
• Right Heart Catheterization: It checks pressure and blood flow in the right side of the heart. Often used in patients with heart failure or pulmonary hypertension.
• Left Heart Catheterization: It focuses on the left chambers of the heart and coronary arteries.

Preparing for the Procedure

• Fasting for 6–8 hours
• Stopping certain medications
• Arranging someone to drive you home afterward

A sedative may be given to help you relax. The area where the catheter enters is cleaned and numbed.

What Happens During the Procedure

• You're awake but sedated
• The doctor inserts the catheter through an artery
• Dye is injected to make vessels visible
• Images are captured in real time
• If necessary, angioplasty or stenting may be done immediately

The procedure typically takes 30 to 60 minutes.

Aftercare and Recovery

• You’ll need to rest for a few hours
• The catheter site is monitored for bleeding
• Drink plenty of fluids to flush out the dye
• Avoid heavy activity for 24–48 hours

Most people go home the same day unless further treatment is needed.

Risks Involved

Though safe, angiography carries minimal risks:

• Bleeding or bruising at the catheter site
• Allergic reaction to the dye
• Irregular heart rhythms
• Rarely, heart attack or stroke

These risks are extremely low in experienced hands.

Benefits of Cardiac Cath

• Precise diagnosis of heart conditions
• Immediate treatment with stents if needed
• Guidance for future interventions or surgery
• Peace of mind through accurate testing
