A CT coronary angiogram (CTCA) is a non-invasive, painless imaging test used to visualise the coronary arteries, which supply blood to your heart. It helps detect blockages or narrowing that could lead to heart attacks.
In advance of the test, you may be given some medication to slow the heart, as the quality of the images on the test will be better at a slower heart rate. Medication may also be given at the time of the test to slow the heart.
You’ll lie down on a narrow table that slides into the CT scanner, which is a large, doughnut-shaped machine. Stickers are attached to the chest to monitor the heart rhythm and a small intravenous (IV) line will be placed in your arm to inject contrast dye. This dye lights up your heart (coronary) arteries on the scan so that the doctor can clearly see any blockages or narrowing.
You might feel a warm or flushed sensation when the contrast dye is injected and some people feel a slight metallic taste in their mouth. This is normal and passes quickly.
The scan itself only takes about 10-15 minutes, although the entire procedure might take 30-60 minutes, including preparation.
The images from the scan will be analysed by a Cardiologist or Radiologist and passed to your treating Cardiologist who will contact you with the results and plan for your ongoing care.
