Coronary Computed Tomography Angiography (Coronary CTA)

What is a Coronary CTA?

A coronary CTA takes pictures of the moving heart and great vessels. This procedure can detect blockages in the coronary arteries.

Preparing for a Coronary CTA

• Do not consume any form of caffeine 8 hours prior to the study.
• Do not eat any solid food for 4 hours prior to the study.
• Do not take medications for erectile dysfunction [e.g., Viagra® (Sildenafil), Cialis® (Tadalafil), and Levitra® (Vardenafil)] for 72 hours prior to the exam.
• Please take all other medications as usual.
• Inform your primary care provider or radiologist if you are having an acute asthma “flare-up” as you should not take Metroprolol (may be given to you as a part of the exam).
• You should always inform your primary care provider and CT technologist if you are or might be pregnant.

Risks or Complications:

Minimal exposure to radiation

Although rare, the intravenous (IV) contrast material involved in some CT scans may cause medical problems or allergic reactions in some people. Most reactions are mild and result in hives or itchiness. In rare instances, an allergic reaction can be serious. Make sure to tell your primary care provider if you have had a prior reaction to contrast material (X-ray dye) during medical tests.

You may be given medication to lower your heart rate. A medical history will be completed before the exam to ensure it is safe for you to take this medication.

How long will a coronary CTA take?

Plan on being at the hospital for several hours.

After Your Procedure

• The radiologist will evaluate your study results and issue a report to your primary care provider.
• Be sure to eat and drink plenty of fluids.
• Arrange to have someone drive you home.
