Coronary angiography is a method of testing for any potential build-up of plaque in the hearts arteries to determine if there is any coronary artery disease present. It involves placing a small catheter through the skin into your artery (from your groin or elbow) and releasing a dye into the coronary arteries for an X-ray to be taken. The procedure will take around 30 to 40 minutes to complete and will require some bed rest after.
The video below will demonstrate step by step how a coronary angiography is performed.
