Cardiac Catheterisation
Topic: Cardiac Catheterization

Cardiac Catheterization

Cardiac catheterization (also called a coronary angiogram) is a test using x-ray dye (contrast material) and x-rays to see the heart and coronary arteries. Since it can show if the arteries are narrowed or blocked, it is often used to determine if bypass surgery is necessary. It usually takes 30-60 minutes to perform the test. If a blockage is detected and needs to be treated right away, an angioplasty (balloon dilation) may be required.


• Normally, angiograms are done in the hospital.
• You will be instructed not to eat or drink for 6-8 hours before the test.
• You will be given a mild sedative to help you relax and an IV will be started in order to give you other medication if needed.
• After an injection of local anesthetic (a numbing medication), a thin catheter (small, flexible plastic tube) is inserted through a small incision in the arm or groin.
• Once in position, dye is injected so that the physician may take an x-ray to see the actual beating of the heart and functioning of the heart valves.
• The dye may cause a feeling like a 'hot flash' or some burning or nausea briefly.
• A bandage is applied to the groin to prevent bleeding.
• You will rest and be observed for several hours after the procedure.


• There is a small risk of developing a stroke during the procedure caused by a blood clot or piece of plaque (blockage) that may be broken off by the catheter. This is a very uncommon complication.
• Other small risks exist for puncturing a blood vessel with the catheter, and developing infection, pain, or swelling at the site of catheter insertion.
• In elderly persons or in those with kidney disease, the contrast material may lead to temporary or permanent kidney failure (rare).
• Allergic reactions to the contrast material can occur, but are usually easily managed.
Following the procedure:

Following the procedure:

• It is common to experience fatigue or soreness from lying in awkward positions during the procedure.
• It is recommended that you drink plenty of fluids after the angiogram to flush the kidneys
