Cardiac Catheterization/Angiogram is a medical procedure used to diagnose and treat some heart conditions.
A doctor places a catheter into your blood vessel and it is threaded to your heart. Dye then is injected through the catheter and flows through your bloodstream, making your coronary arteries visible with the use of radiation through X-ray.
The dye shows whether cholesterol and plaque has built up inside your coronary arteries. Plaque can narrow or block the arteries or restrict blood flow to the heart.
Cardiac catheterization causes little or no pain and rarely causes serious complications.
A peripheral angiogram uses X-rays to determine whether there are narrowed or blocked arteries within the arms and lefts.
