 CT Angiography (CTA) provides comprehensive, non-invasive imaging of your coronary arteries.
A revolutionary advancement in detecting heart disease.
What is Coronary Artery Disease?
Our bodies deposit fatty material called lipids inside our blood vessels and then gradually solidifies these deposits with calcium. These “plaques” are what cause coronary artery disease.
What is CT Angiography?
CT Angiography (CTA) is a procedure that uses a 64-slice CT scanner and intravenous contrast to see the detailed anatomy of blood vessels of the heart as well as other blood vessels in the body.
Why is CT Angiography an excellent alternative to Catheter Angiography?
While standard catheter Angiography is still considered the gold standard for diagnosing disease of blood vessels, it does require insertion of a catheter into an artery in the groin as well as a post procedural recovery for up to six hours. CTA is less invasive and more patient friendly procedure. Contrast is injected into a vein, which is technically less difficult and has a very low risk of complications. As a result, patients typically leave in less than an hour with no downtime or recovery and can resume normal activities. Result of procedure is available immediately.
How is the procedure performed?
After obtaining IV access you will be placed on the CT scanning table and given intravenous contrast while the CT Scanner acquires images. You will be ask to hold your breath for 10-15 seconds. Commonly medication will be given with the Coronary scan to slow your heart rate. Some people experience a temporary warming sensation while the contrast is infused. This will dissipate rapidly. At the end of the scanning the IV is removed. Once the images are processed, a cardiologist will review the results with you.
Is there any risk in this procedure?
There is a risk of an allergic reaction—which may be serious—whenever contrast material containing iodine is injected. If you have a history of allergy to x-ray dye, your doctor may advise that you take special medication before the CTA to lessen the risk of allergic reaction.
CTA can be performed with caution in patients with kidney, disease, because contrast material can further harm kidney function. Before your exam a blood test will check the kidney function
