Coronary CT Angiography of the Heart

What is a coronary CT angiography (CCTA) of the heart?

A computed tomography (CT) scan is a noninvasive exam. A coronary CT angiography (CCTA) is a scan that produces 3-D images of your coronary veins and arteries.

Why has my physician ordered this exam?

CCTA does not carry the invasiveness or recovery time associated with an older method of examining coronary arteries (cardiac catheterization, also called heart catheterization or catheter angiography).

This exam can help your physician evaluate you for various coronary conditions, including:

  • Aneurysm
  • Calcium buildup
  • Coronary heart disease
  • Dissection
  • Pulmonary embolism
  • Soft plaque buildup

CCTA is usually not suitable for patients with acute cardiac symptoms. Because those patients may require further, immediate intervention, cardiac catheterization remains the preferred testing method.
