The catheter will be inserted into an artery in either the groin or arm. It is usually inserted at the crease opposite the elbow or at the wrist. The insertion area will be shaved, cleaned, and numbed. A needle will be inserted into a blood vessel. A wire will be passed through the needle and into the blood vessel. The wire will then be guided through until it reaches your heart. A soft, flexible catheter tube will then be slipped over the wire and threaded up to your heart.
The doctor will be taking x-ray pictures during the procedure to know where the wire and catheter are. Dye will be injected into the arteries of the heart. This will make the arteries and heart show up on the x-ray images. You may feel warm during the dye injection.
