What is a CT Coronary Angiography (CTCA)?

A CT Coronary Angiography (CTCA) is a non-invasive imaging test that uses computed tomography (CT) to visualize the coronary arteries. It helps detect blockages or other abnormalities in the coronary arteries that could lead to heart problems.

What happens during a CT Coronary Angiography (CTCA)?

During a CT Coronary Angiography, you will lie on a table that slides into the CT scanner. A contrast dye is injected into a vein in your arm to enhance the visibility of your coronary arteries. The scanner takes detailed images of your heart and its blood vessels, which are then analyzed by a radiologist.

Why would I need a CT Coronary Angiography (CTCA)?

You might need a CT Coronary Angiography if you have symptoms suggestive of coronary artery disease, such as chest pain or shortness of breath. It helps detect the presence and extent of blockages or other coronary artery abnormalities, guiding treatment decisions.

Who needs a CT Coronary Angiography (CTCA)?

A CT Coronary Angiography may be necessary if you have the following symptoms:

• Patients with symptoms of coronary artery disease
• Individuals with inconclusive results from other cardiac tests
• Individuals with a high risk of heart disease

What are the risks of a CT Coronary Angiography (CTCA)?

CT Coronary Angiography is generally safe but involves some risks, including:

• Exposure to radiation and potential allergic reactions to the contrast dye
• In rare cases, kidney problems may occur, especially in patients with pre-existing kidney conditions

It’s important to note that these risks are rare, and the benefits of the test typically outweigh the risks. Additionally, the test is performed under the supervision of trained medical professionals who are equipped to handle any complications that may arise.

How do I prepare for a CT Coronary Angiography (CTCA)?

To prepare for a CT Coronary Angiography:

• Follow your doctor’s instructions, which may include fasting for a few hours before the test
• Inform your provider of any allergies, especially to contrast dye, and discuss any medications you are taking
• Wear comfortable clothing and be prepared to remove any metal objects that could interfere with the imaging
