Deprecated: Aortic Valve CT Angiography with Contrast
A CT scan uses contrast and imaging to examine the aortic valve and nearby blood vessels. It may help assess valve narrowing, calcification, and surrounding anatomy.
["This imaging test evaluates the aortic valve and nearby blood vessels for narrowing or structural abnormalities."]

What is this test?
Aortic valve CT angiography is a computed tomography scan that creates detailed pictures of the aortic valve, the aorta, and nearby blood vessels. Intravenous contrast may be used to improve the images. This test is marked as deprecated in the source listing.
Why might I need this test?
Your clinician may order this imaging study to evaluate a suspected aortic valve problem, especially when symptoms or other tests suggest narrowing or obstruction. It can also help assess the valve and surrounding vessels before certain procedures or when other imaging is inconclusive.
How is the test performed?
You lie on a table while a CT scanner takes X-ray images from different angles. If contrast is used, it is usually given through a vein in your arm, and the scan may include images before and after the contrast is administered.
How do I prepare for the test?
Follow the instructions provided by the imaging center, which may include avoiding contrast for a period beforehand if you have a prior contrast reaction. Tell the care team about kidney problems, allergies, pregnancy, and any other medical conditions before receiving contrast.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
The scan may show aortic valve narrowing, thickening, or calcification, as well as abnormalities in the adjacent aorta or other blood vessels. Findings can help guide decisions about further heart evaluation, procedure planning, or treatment. Results should be interpreted together with symptoms, physical examination, and other cardiac tests.
Short name
