A cardiac catheterization is a procedure in which the physician passes a long, thin tube through a blood vessel into your heart. This tube, called a catheter, may be introduced through a vein or through an artery. Sometimes vessels in the leg are used, and sometimes those in the arm are used. The kind and location of the vessel used vary with the information that is needed.
