When the catheter reaches the correct spot, the doctor uses it for treatments or does tests on the patient’s heart, explains the National Heart, Lung and Blood Institute. In order to determine the right spot to put the tip of the catheter, special X-ray movies are taken of the catheter and the guide wire as they are moved into the heart. During the procedure, the doctor may use a special type of dye that flows through the bloodstream to the heart, making the coronary arteries visible on the X-ray pictures. After the needed treatments or tests are performed, the doctor pulls back the catheter along with the sheath, closing up and bandaging the opening left in the blood vessel.
