Coronary Angiography

Coronary Angiography is a procedure which uses X-rays and a special dye that enables the doctor to see any abnormalities in chambers of the heart, blood vessels and the pattern of flow of blood to the heart. It is used to:

• Detect any blockages or abnormalities
• Take a blood or muscle sample
• Measure blood pressure and oxygen levels
• Detect congenital heart defects

How do I prepare for the procedure?

• Do not eat or drink anything for 8 hours prior to your appointment time.

How is the procedure performed?

Cardiac catheterization is usually performed in a hospital. A mild sedative is given to keep you comfortable during the procedure. A thin tube called a catheter is inserted into a blood vessel in the arm, groin or neck area and then guided to the heart.

A special fluid (called a contrast medium or dye) is then injected into the catheter and X-ray images are taken. The pictures produced are called angiograms. The fluid that is injected is visible on the X-rays, so the angiograms show up all the blood vessels that the fluid travels through.

It is a safe procedure with little to no pain and a low risk of complications.
