CT Coronary Angiography (CTCA)

CT Coronary Angiography (CTCA) involves the injection of iodinated contrast into a vein and the use of x-rays and computer tomography to generate a 3-dimensional image of the heart.

This procedure is most often used to non-invasively assess the coronary arteries and is highly accurate at excluding coronary artery disease. It can also be used to evaluate the cardiac structures (e.g. aortic valve) prior to cardiac surgery such as transcatheter aortic valve implantation (TAVI).

As part of the test, CTCA also provides calcium scoring to evaluate the extent of coronary atherosclerosis.

This procedure is performed at the Princess Alexandra Hospital through the Radiology department.
