A coronary angiogram evaluates your heart’s valves, pumping function, and heart arteries by using an x-ray technique called fluoroscopy. Images of your heart are taken in “real time” and provide a permanent record of your condition. A long, thin, flexible tube called a catheter is inserted into a blood vessel in your groin (upper thigh), or arm and threaded to your heart.
A special dye is injected to highlight your heart and blood vessels so images may be taken. Coronary angiography is primarily a diagnostic procedure designed to identify whether or not you have disease in your heart arteries.
