CT Coronary Angiography

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.
