Angiography is an X-ray examination of your veins, arteries and heart chambers that looks at blood flow. Angiography may be used to identify the sites where the arteries have become narrowed or blocked and can also reveal any blood clots, calcium deposits or any weakening or bulging of your artery walls (aneurysms ). An angiogram is often needed to decide what treatment is necessary for your heart failure.
A fine, flexible, hollow tube (catheter) is inserted into a blood vessel in your groin or arm. The tip of the tube is positioned either in the heart or at the entry of the arteries supplying the heart before a special dye is injected, visible by X-ray. The pictures obtained are known as angiograms.
