Coronary Anatomy and Angiography

The purpose of coronary angiography is to accurately define coronary anatomy, and obtain optimal angiographic images of the main epicardial coronary arteries and their branches. It is important to limit radiation exposure to the patient and medical personnel while trying to obtain the essential number of images to define the anatomy, and minimize contrast use. Information obtained from coronary angiography is significant because it assists in the diagnosis and therapeutic intervention of coronary artery disease. Inadequate knowledge of coronary anatomy and angiographic views can lead to serious complications, inappropriate interventions, and wasteful healthcare expenditures.
