Coronary Angiography

Angiography involves inserting a long, thin tube, called a catheter, through a vessel in your arm or leg and into the coronary arteries of your heart. A dye is injected into the catheter, and an x-ray is then used to watch the movement of the dye through your blood vessels and to note the exact location and size of any blockages. An angiogram is an "invasive" procedure, and carries a slight risk of complications. Angiography is generally recommended for women with severe symptoms who do not respond to treatment or whose other tests did not provide enough information. Again, since an angiogram exposes you to a small amount of radiation, tell your healthcare provider if you think you might be pregnant before taking this test.
