CT Coronary Angiogram (CTCA)

CT Coronary Angiogram (CTCA)

CT Coronary Angiogram (CTCA)

We refer all WA Heart Clinic patients requiring a CT coronary angiogram to a local radiology clinic for their procedure.

Also known as a CTCA, a CT coronary angiogram is a scan that provides information about your heart structure. It is a non invasive way of looking for coronary artery disease. The CT images are taken after slowing down your heart with medications and injecting a dye into your vein. This dye highlights any coronary artery narrowing or blockages, which help to diagnose coronary artery disease.

PATIENT INFORMATION: Before your appointment, please read our patient information page with essential information on our location, parking, payment options and more.

Why do I need a CT coronary angiogram

Your doctor may recommend a CTCA if you have:

  • Symptoms of coronary artery disease, such as:
    • Chest pain
    • Difficulty breathing
    • Pain or discomfort in your arms, back, stomach, left shoulder, neck or jaw
    • Indigestion like chest pain
  • An elevated risk of heart disease based on your medical and family history.
Risks and complications

Severe reactions to CTCA are rare. However, some reactions are possible, such as:

  • Headache due to medications given during the procedure
  • Allergy to the x-ray dye (please tell the doctor if you have a history of allergies)
  • Kidney problems from the x-ray dye (possible in patients with a history of kidney problems)
Do I need to prepare for CT coronary angiogram?

The radiology clinic will give you instructions to prepare for the CT coronary angiogram.

What happens during CT coronary angiogram?
  • You’ll be taken to a procedure room and asked to put on a hospital gown
  • You will lie down on a narrow CT scanning bed
  • A technician will connect you to a heart rate monitor
  • A cannula will be placed in your arm, and x-ray dye will be injected
  • You’ll be asked to lie still and hold your breath while the technicians take each image
What happens next?

You’ll be taken to a recovery area, and the cannula will be removed from your arm. The medical team will monitor you and make sure you’re recovering well. Once you’re feeling well enough, you can go home. You should be well enough to drive home if you prefer. The doctor will organise a follow-up appointment to talk about the results of your CTCA.
