Angiogram (cardiac catheterization)

The procedure is uses X-ray imaging to diagnose any serious coronary artery disease and is done in the hospital's cardiac catheterization lab. 

What to expect

Patients are usually given a sedative to help them relax. During the procedure, a long flexible tube called a catheter is inserted into an artery, usually through an incision in the groin, and gently directed toward the heart. Once there, a special dye that can be seen by an X-ray machine is injected and images of the blood vessels are taken to look for blockages.

Recovery

• You will be given specific wound-care instructions before you leave.
• You may experience some soreness where the catheter was inserted as the numbness wears off.
• Do not drive for at least 12 hours after the procedure.

Afterward, your heart-care team may recommend a follow-up program to assist in your recovery.
