CORONARY ANGIOGRAPHY: HOW IS ANGIOGRAPHY PERFORMED?

The procedure is performed from the groin under local anaesthesia. On the day of the angiography you will need to be fasting for 4-6 hours. Your groin will be shaved. A needle will be placed in your arm vein and medication may be administered to you before, during or after the investigation. During the procedure you will be asked to lie on the catheterisation table, your groin will be cleaned with antiseptic solution and you will be draped with sterile towels. Electrodes will be attached to your chest to enable ECG recording throughout the procedure. You will have to lie immobile on your back during the angiography with your arms folded and your hands under your head. A sheath (tube) will be inserted into your right groin (occasionally left) and a catheter will be introduced through your aorta up to your heart and coronary arteries. Pressures will be taken from the heart chambers and iodine containing dye will be injected to take pictures of the coronary arteries and the chambers of the heart. You may be asked to assist during the procedure by breathing deeply, holding your breath or coughing. These manoeuvres are necessary to improve visualisation of the coronary arteries.

The procedure lasts 10-15 minute After the angiography is over t catheters and the sheath in your leg are removed and tight bandage applied over the groin. For a few hours after that you will be required lie on your back and keep your leg straight. Lying almost immobile in bed is difficult, but is necessary in order to prevent bleeding from the groin. You will be allowed to get up from bed after 4-6 hours and may return home the same night, or maybe the next morning. You can take fluids immediate after the procedure and solid food 15-30 minutes later. You should drink lots of fluids (water, juice, beverages) after the procedure. This ensures that the dye used 1 angiography gets quickly washed away in the urine.
