Cardiac catheterization

Cardiac catheterization

You will be awake and able to follow instructions during the catheterization. A mild sedative is usually given 30 minutes before the procedure to help you relax. The procedure may last from 1 to several hours.

You may feel some discomfort at the site where the IV is placed. Local anesthesia will be used to numb the site, so the only sensation should be one of pressure at the site. You may experience some discomfort from having to remain still for a long time.

After the test, the catheter is removed. You might feel a firm pressure at the insertion site, used to prevent bleeding. If the IV is placed in your groin, you will usually be asked to lie flat on your back for a few hours after the test to avoid bleeding. This may cause some mild back discomfort.

Cardiac catheterization is usually performed to evaluate heart valves, heart function and blood supply, or heart abnormalities in newborns. It may also be used to determine the need for heart surgery.

Therapeutic catheterization may be used to repair certain types of heart defects, open a stenotic heart valve, and open blocked arteries or grafts in the heart.
