A conventional angiogram involves several injections of contrast dye via a thin tube (catheter) placed directly in the heart arteries. Placing the catheter is invasive – it has to be put in position by passing it through a small incision in the groin into the main leg artery and up to the heart via the aorta. Once the procedure is finished and the catheter withdrawn, you will need to lie still for several hours with a heavy weight over the incision to minimize the risk of leakage.
Coronary CT Angiogram
The coronary CT angiogram (CTA) is a diagnostic scan that is used to determine if any of the coronary arteries supplying blood to the heart are narrowed or becoming blocked.
This procedure is recommended if:
· You have symptoms such as chest pain which might suggest a narrowing of your heart arteries
· You have had an EBCT scan or other tests that show significant coronary artery disease
· You are at risk of heart disease and wish to have a definitive answer as to whether you have any ‘furring up’ of your heart arteries, including the dangerous soft cholesterol-rich plaques
· Your previous coronary artery angioplasty, stent or bypass graft needs to be checked for a blockage
· You need, or would like, a less invasive alternative to a conventional angiogram.
