What is Coronary Angiography?
You will be given a local anesthetic in your groin or your wrist. An incision (cut) is made and a catheter (a fine, flexible, hollow tube) is passed into an artery in your groin or wrist. During the procedure, some dye is injected into the catheter to make your coronary arteries show up on the X-ray.
You may feel warm flushing feeling when this happens. The doctor will pass the catheter into your coronary arteries, to see if there are narrowing within them.
If the coronary angiogram shows that a section of one or more of your coronary arteries is severely narrowed, your cardiologist may advise you to have either:
- A coronary angioplasty—Also called PCI (Percutaneous coronary intervention)
- Coronary bypass surgery.
