A special procedure that takes dynamic x-ray pictures of your heart. The purpose of this procedure is to see if your coronary arteries are narrowed or blocked and to look for abnormalities of your heart muscle or heart valves. Another term for coronary angiogram is cardiac catheterization.
A slender catheter (a thin, hollow plastic tube) is threaded through the largest artery in your body (the aorta) via the wrist or the groin artery until it reaches the coronary arteries of the heart. A special x-ray sensitive dye (contrast) is injected, and dynamic x-rays are taken of the blood vessels as the contrast moves through them.
