What is a CTCA?
A CT coronary angiography (CTCA) is a scan that takes pictures of the coronary arteries of a beating heart. A liquid contrast agent is injected into a vein in the arm to increase the density of the blood in the vessels, which allow the inside and outside structure of the blood vessels to be seen more clearly on the CT scan.
It is NOT an invasive coronary angiogram.
Why would I need a CTCA?
A CTCA is predominantly used to check for narrowed or blocked arteries in your heart, but it can also be used to check your heart for various conditions. It can be used to look at structures around the heart and plan more complex structural heart interventions.
Are there any risks with having a CTCA?
Due to the nature of an X-ray, you will be exposed to some radiation during the test, although depending on the machine will depend on the amount of radiation used. It is best to speak to your consultant cardiologist if you are pregnant.
In addition, contrast X-ray dye is given that can affect the kidneys and in rare cases can cause an allergic reaction.
What is CaRi-Heart® and what is it used for?
CaRi-Heart® is a non-invasive technology developed by cardiologists at Caristo, that can be applied to analyse any routine CT coronary angiogram to accurately predict a patient’s risk of a heart attack – years in advance. If increased levels of coronary inflammation are identified, we can provide you with a personalised prevention and management plan.
What is Heartflow Analysis and what is it used for?
Heartflow is a brand new piece of technology available for coronary CT patients. It offers two different types of analysis:
- FFRCT Analysis - this is a non-invasive test that provides a personalised, colour-coded 3D model of your coronary arteries measuring how plaque build-up may be impacting blood flow. This test provides the most accurate diagnosis of coronary artery disease.
- Plaque Analysis - this shows the amount, type and location of plaque in your arteries. This information helps guide your personalised treatment plan. Plaque Analysis can identify higher-risk plaques that do not appear on a calcium score scan and are most likely to cause a cardiac event.
How Heartflow works:
- Scan - Detailed images of your heart are taken with a non-invasive coronary CT angiogram (CCTA).
- Measure - the CCTA images undergo advanced AI processing to generate a personalised, 3D model of your arteries. Your report will analyse blood flow and plaque build-up in your coronary arteries.
- Act - With all the information in hand, you and your consultant can make an informed choice on the best reatment pathway for you.
