CT Coronary Angiography (CTCA)
What is an 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 an 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 an 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 an CT Coronary Angiography (CTCA)?
An 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 an 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. Your doctor will review your medical history and assess your overall health to determine whether the benefits of the test outweigh the risks for you. If you have concerns about the risks of a stress echocardiogram, be sure to discuss them with your doctor before the test.
How do I prepare for an CT Coronary Angiography (CTCA)?
​
To prepare for a CT Coronary Angiography:
-
Follow your doctors 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
