How and Why an Angiogram Is Obtained

In a coronary angiogram, a catheter is inserted into an artery in the groin, arm or neck and threaded through the blood vessels to the heart. A coronary angiogram can show blocked or narrowed blood vessels in the heart. A coronary angiogram is a procedure that uses X-ray imaging to see your heart’s blood vessels.

Why would an angiogram be ordered?

An angiogram can show if your coronary arteries are narrowed, where they are narrowed, and by how much. It can help your doctor see if a change in treatment—such as medicines, angioplasty, or coronary artery bypass surgery—can improve your angina or lower your risk of heart attack or death from heart problems.

What can an angiogram diagnose?

A long flexible catheter is inserted through the blood stream to deliver dye (contrast agent) into the arteries making them visible on the x-ray. This test can help diagnose a stroke, aneurysm, arteriovenous malformation, tumor, clots, and arterial stenosis.
