CT Coronary Angiogram

At Imaging Associates, we offer advanced CT Coronary Angiogram (CTCA) examinations to assess cardiovascular health with precision and efficiency.

Computed Tomography Coronary Angiograms are usually recommended for patients with multiple cardiovascular risk factors, chest pain, or a history of cardiac surgery. Common risk factors include smoking, diabetes, high blood pressure, a family history of heart disease, and high cholesterol levels.

What is a CT Coronary Angiogram?

A CT Coronary Angiogram is a non-invasive imaging procedure that uses computed tomography technology to view the supply of blood to the heart. While conventional angiogram is still considered to be the gold standard in detecting coronary artery disease, a CT Coronary Angiogram is less invasive than traditional angiography. CT Coronary Angiography does not require hospitalisation, and CTCA scanners are able to scan extremely quickly, so they can capture the heart in a single beat. The advanced CTCA scanning equipment used by Imaging Associates enables us to view and capture images of the entire heart in a single heartbeat.

Preparing for a CT Coronary Angiogram

If you are referred by your doctor or specialist for a CT Coronary Angiogram, there are a few simple steps that will ensure your scan is effective and stress-free:

• Prior to your scan, your referring physician may prescribe medication to lower your heart rate if necessary. This may have to be taken a couple of days before the scan, depending on your initial heart rate.
• On the day of your CTCA scan, you will need to fast for 2 hours prior to your procedure. It is important to remain hydrated, but you must avoid caffeine, stimulants, alcohol, and heavy exercise.
• Upon arrival at Imaging Associates, our staff will explain the procedure to you and answer any questions you might have. A brief medical history will be taken, and your heart rate and blood pressure will be recorded. If your heart rate is above 60, medication may be administered to lower it. Typically, it can take between 30 minutes and 1 hour for your heart rate to lower.
• Once your heart rate is optimal, you will be asked to change into a gown, ECG leads will be placed on your back and you will lie down on the CT table, where a cannula will be inserted in the vein near your elbow. A contrast dye will be administered through the cannula, so that images of your heart can be captured. At this stage some patients may feel hot, experience a distinctive taste in the mouth or feel the need to urinate. These sensations are brief, generally lasting only 5-10 seconds.
• After the heart CT scan, you will need to remain in the clinic for a short observation period to monitor for any potential reactions. Once cleared, you can go home.

Risks and Considerations

While CT Coronary Angiograms are generally safe, potential risks include contrast reactions, extravasation of the contrast into the tissue instead of the vein, and medication side effects. It’s essential to stay hydrated before and after your scan, especially for diabetic patients who should also have a kidney function blood test within one month prior to your CT Coronary Angiogram.

Interpretation and Treatment Planning

The results of a CT Coronary Angiogram play a vital role in treatment planning and patient management. Depending on the findings of the scan, further evaluation with a conventional coronary angiogram may be recommended. Additionally, medication and lifestyle adjustments, and ongoing monitoring may be necessary to optimise cardiovascular health. This can be discussed with your referring physician.
