A coronary angiogram, also known as cardiac catheterisation, is a diagnostic procedure by passing a flexible tube called catheter into the blood vessels of the heart. This catheter can be threaded through your blood vessels to your heart via a groin (femoral) or wrist (transradial) approach. A type of dye that is visible by an X-ray machine is injected into the blood vessels of your heart and a series of images are taken.
Not to be confused with a CTCA, which is a non-invasive imaging technique that does not involve any insertions.
If the angiogram finds severe narrowing in your artery, your cardiologist may perform a Coronary Angioplasty for you immediately
