Coronary angiography


Coronary angiography is a process that uses a specific dye and x-rays to observe the flow of blood in the arteries of the heart. It is performed to find out if your coronary arteries are blocked or narrowed, and if so, where and by how much. A mild sedative is given before initiating the test to relieve anxiety. A thin hollow tube is passed through an artery and it reaches to the heart. The injection of dye takes place and its movement is observed through x-ray images.
