Coronary angiography

Coronary angiography via cardiac catheterization is considered the "gold standard" of heart disease tests.

What makes coronary angiography a superior test compared to the others?

During coronary angiography, doctors guide a catheter into the coronary arteries. Next, a small amount of radiographic contrast (a solution containing iodine, which is easily visualized with X-ray images) is injected into each coronary artery. X-ray images are then taken, which are called the angiogram. Angiographic images accurately reveal the extent and severity of all coronary arterial blockages.
