Coronary angiography






Coronary angiography is performed to detect obstruction in the coronary arteries of the heart. During the procedure a catheter (thin flexible tube) is inserted into an artery in your arm or groin and then threaded carefully into the heart. The blood vessels of the heart are then studied by injection of contrast media through the catheter. A rapid succession of X-rays (fluoroscopy) is taken to view blood flow.
