A coronary angiogram is a procedure that uses X-ray imaging to see your heart's blood vessels. Coronary angiograms are part of a general group of procedures known as heart (cardiac) catheterization.
Heart catheterization procedures can both diagnose and treat heart and blood vessel conditions. A coronary angiogram, which can help diagnose heart conditions, is the most common type of heart catheterization procedure.
During a coronary angiogram, a type of dye that's visible by an X-ray machine is injected into the blood vessels of your heart. The X-ray machine rapidly takes a series of images (angiograms), offering a detailed look at the inside of your blood vessels. If necessary, your doctor can perform procedures such as an angioplasty during your coronary angiogram.
What Is Coronary Angioplasty?
Your heart’s arteries can become blocked or narrowed from a buildup of cholesterol, cells or other substances (plaque). This can reduce blood flow to your heart and cause chest discomfort. Sometimes a blood clot can suddenly form or get worse and completely block blood flow, leading to a heart attack.
Angioplasty opens blocked arteries and restores normal blood flow to your heart muscle. It is not major surgery. It is done by threading a catheter (thin tube) through a small puncture in a leg or arm artery to the heart. The blocked artery is opened by inflating a tiny balloon in it.
