Cardiac catheterization is a heart procedure used to diagnose heart disease. During the procedure, a catheter (inserted into an artery in your arm or leg) is guided to your heart, contrast agent is injected, and X-rays of the coronary arteries, heart chambers, and valves are taken.
Peripheral Angiography is an out-patient procedure that helps find blood vessel problems in the lower body and legs. Because arteries do not show up on ordinary x-rays, arteriograms utilize a “contrast agent” containing iodine, which is injected into the arteries to make them visible on radiographs. It makes a “map” of the vessels (arteries) that carry blood through the body. This map can show where blood flow may be blocked. Blockages can cause painful leg cramps while walking. They can also keep foot wounds from healing. Problems with the arteries may lead to a variety of complications such as stroke, high blood pressure or leg pain.
