Coronary Computed Tomography Angiography

What is coronary computed tomography angiography?

Computed tomography (CT scan) uses X-rays and computer technology to produce three-dimensional images of soft tissues, bone, organs, and other structures inside the body. CCTA is a specialized diagnostic imaging test that identifies plaque buildup in the coronary arteries, the vessels that supply blood to the heart. 

Plaque contains fat, cholesterol, and other substances that harden and block blood flow, a condition known as atherosclerosis. In turn, atherosclerosis significantly increases risk factors for a heart attack or other cardiac event.

Chinatown Cardiology offers CCTA scans in-office. The experienced cardiology team uses Cleerly analysis software to translate CCTA test results into a comprehensive report.

The Cleerly report provides valuable information you can use to understand your risk for heart disease. Your cardiologist can also review existing heart health issues so that you can explore your options for treatment.

Why would I need a coronary computed tomography angiography?

You may need a CCTA scan if you have symptoms of cardiovascular disease, such as:

• Dizziness
• Chronic fatigue
• Heart palpitations
• Chest pressure or pain
• Shortness of breath
• Swelling in legs, feet, or ankles

The Chinatown Cardiology team might also request a CCTA if your results from a stress test, electrocardiogram (EKG), or echocardiogram are abnormal, or if you’re at increased risk for heart disease because of unhealthy lifestyle choices or genetic factors.

What happens during a coronary computed tomography angiography?

During a CCTA, your Chinatown Cardiology specialist injects a contrast dye material that travels through your blood vessels, including the coronary arteries. The contrast dye makes the vessels appear bright white under X-ray technology, making the images clear for diagnostic purposes.

You may also need to take medication before your scan to slow your heart rate for better picture quality. Additionally, your provider might ask you to hold your arms over your head during the scan for clearer images.

A CCTA scan doesn’t take long to complete, and you can expect to return to your usual activities immediately.

Your cardiologist reviews your scan results and discusses any additional testing or treatments you need.
