Coronary Catheterization

Coronary catheterization (pronounced: kuh-ROH-nuh-ree kath-uh-tuh-ruh-ZAY-shun) is a medical procedure used to diagnose and treat certain cardiovascular conditions.

Etymology

The term "coronary" comes from the Latin corona, meaning "crown", and refers to the crown-like circle of blood vessels seen encircling the heart in anatomic drawings. "Catheterization" is derived from the Greek katheter, meaning "to send down", and refers to the process of inserting a thin tube, or catheter, into a body cavity or vessel.

Procedure

During a coronary catheterization, a long thin tube called a catheter is inserted in an artery or vein in your groin, neck or arm and threaded through your blood vessels to your heart. This allows doctors to conduct diagnostic tests and treatments on the coronary arteries and heart.

Related Terms

  • Angiogram: An X-ray image of the blood vessels.
  • Cardiovascular: Pertaining to the heart and blood vessels.
  • Coronary Arteries: The two arteries that branch from the aorta to supply blood to the heart.
  • Stent: A small mesh tube that’s used to treat narrow or weak arteries.

Risks

Coronary catheterization carries a risk of complications, including heart attack, stroke, injury to the artery where the catheter was inserted, irregular heart rhythms, allergic reactions to the dye or medication, kidney damage, infection, and bleeding.
