What is cardiac catheterization?

Tubes & X-Ray Info. A tube in inserted via a peripheral artery &/or vein, passed through the vessel to the heart arteries & into &/or through the heart chambers to measure pressure, blood flow &/or "see blood" via dye injected into the blood flowing through artery(s) &/or vein(s) near/around heart. Dye in the blood makes blood column show on X-Ray for a few seconds to see outline of artery &/or heart chamber opening.
Angiogram. If your doctor suspects you have significant coronary artery disease, he or she may recommend that you undergo cardiac catheterization (also called an angiogram). During catheterization, x-ray dye is injected into the coronary arteries and pictures are taken. In patients with coronary artery disease, the pictures show the actual blockages and their severity.
See below. A long, thin, flexible tube called a catheter is put into a blood vessel in your arm, groin (upper thigh), or neck and threaded to your heart.Your doctor may put a special type of dye in the catheter. The dye will flow through your bloodstream to your heart. Then, your doctor will take x-ray pictures of your heart. The dye will make your coronary (heart) arteries visible on the pictures.

What are cardiac catheterization procedures?

X-ray test. During cardiac catheterization, x-ray dye is injected into the heart while x-ray movies are taken during the injection. This allows the physician to see the muscle of the heart, the function of the valves, and the coronary arteries. As the heart structures are not dense like a bone, it requires x-ray dye to be injected in order to be able to see the important structures of the heart. Read more...

What purpose does cardiac catheterization serve?

Look at heart artery. A cardiac catheterization is usually an outpatient procedure wher a small hollow tube is placed under local anesthesia into the artery of the arm or leg and advanced to the heart. Iodinated contrast can be injected into the arteries and into the chambers of the heart to help diagnose and treat heart artery blockage and valve problems. Read more...
Cath . This test allows your doctor to visualize the coronary arteries (blood flow to your heart), and take pressure measurements in the chambers of your heart in order to determine if there are problems. If a blockage is found in an artery, then it can be fixed with a stent via catheterization. Read more...

For what conditions is cardiac catheterization recommended?

Long list. A very large number of cardiac conditions may possibly require cardiac catheterization. These abnormalities may involve the lining of the heart (pericardium), the muscle of the heart (myocardium), the valves of the heart, or the arteries of the heart (coronary arteries). Read more...
