Cardiac Angiography
Cardiac Catheterization and Angiography are techniques that can be used to diagnose many types of heart disease, but most commonly, it is used to diagnose the presence of coronary artery disease (CAD). Blockages or narrowings of the heart arteries can be seen by injecting a fluid through them that can be seen under x-ray (contrast). Contrast can also be used to fill the left ventricle (the main pumping chamber) to evaluate its function. Cardiac catheterization can also be used to diagnose certain types of valve disease, pulmonary hypertension, or congenital (present from birth) heart disease.
