Coronary Angiography, Angioplasty and Stenting angioplasty/stenting will be performed. It is a sterile area, so everyone in the room will wear gowns, masks, and caps. You will lie flat on your back and during the entire procedure your condition will be monitored closely - ECG, heart rate, blood A coronary angiogram is a special x-ray procedure in which pressure, breathing rate, and oxygen level. Images of the we take pictures of the coronary arteries after injecting a catheter being moved through the body into the heart and dye which allows us to see blood flowing inside the arteries the structures of the heart as the dye is injected are displayed to show whether they are narrowed or blocked. Although a coronary CT can be done it involves a much bigger radiation The catheter site (groin or wrist) will be cleansed again with dose and may not show the inside of the arteries when there antiseptic soap, sterile towels and a sheet will be placed are heavy deposits of calcium in the wall.

Local anaesthetic will be injected into the We are also able to measure blood flow using special flow skin and the cardiologist will make a small cut in the skin at wires, allowing us to decide whether a narrowing is actually the insertion site before putting a plastic tube into the blood limiting blood flow. Using a combination of pictures (the vessel which is advanced towards the heart and then into angiogram) and flow data helps us decide on treatment the opening of the coronary arteries in the aorta where dye is options, often proceeding to treatment with a balloon injected to see if there are any blockages and where they are (angioplasty) or stent (stenting) at the same time.
It is very important for you to remain still during the procedure. When the dye is injected, you may notice a feeling of warmth or even a hot flash. Occasionally a little You must have nothing to eat or drink for at least six hours pressure or discomfort is felt but this sensation will last before your procedure.

If you take diabetic medication you need to bring your tablets and insulin with you but withhold all medication on the morning of your procedure. In the case of metformin (Diabex, Diaformin) this is stopped 24 hours before and 48 hours after If coronary disease is found and angioplasty/stenting is your procedure. possible and appropriate, the interventional cardiologist may perform these procedures immediately following the angiogram if they and your treating cardiologist agree this is appropriate. This involves positioning a small wire well This test is done as a day stay procedure in hospital by a beyond the narrowed area inside the artery which is then cardiologist who will explain the procedure to you before used as a guide to place appropriate balloons and stents it is done.

If your groin was punctured, it is important to keep your leg straight for the duration of the monitoring period, alternatively if your wrist was punctured, avoid bending that wrist or using your hand during the monitoring the period. You will have frequent observations of your pulse and blood pressure, and checks made of your puncture site by the nursing staff. Chest pain after the procedure should be reported to the nursing and medical staff promptly. If you have had an angiogram only, you are usually allowed to leave hospital on the day of the procedure depending on the results of the test and the advice of your treating and interventional cardiologist. If you have an angioplasty and stenting, you will stay in the hospital at least overnight and usually be allowed home the next morning. A follow-up appointment will be made with your cardiologist usually within a week or two and you will be discharged with appropriate medications. Please see your family doctor one week after your procedure to have the puncture site checked. The test results will generally be discussed with you at your follow up appointment with your cardiologist.
After discharge from hospital you should not drive for 48 hours after the procedure. Drink plenty of fluids over the next eight hours as this helps flush the X-ray contrast out of your system. If possible, have someone stay with you at home the night of your procedure. The plastic dressing can be removed from the puncture site (wrist or groin) the day after the procedure following your shower.
You should avoid heavy lifting the week after the procedure.
