Having a CTCA Scan
This procedure is undertaken in one of out partner facilities. A CTCA scan is performed with you going into a metal tube. You have to lie still to allow the pictures to be taken. A drug may need to be given to slow your heart rate down. The test involves the use of X-rays and X-ray dye, which is injected via a needle in the back of your hand. There has been great progress in taking pictures of the heart and brain blood vessels. The radiation dose of the CT scan is often equivalent the coronary angiogram. In addition, X-ray contrast dye still has to be used. However, it is less invasive than the angiogram and so will be the diagnostic tool of choice in some cases. You cannot do coronary angioplasty (PCI) guided by CT angiography alone. We may do a CT scan to look at just your coroary arteries, or look at the whole of your heart and aorta, to assess if you are suitable for TAVI.
