Cardiac Catheterization

Cardiac catheterization is a test that uses a catheter (tube) and x-ray machine to assess the heart and its blood supply. It is generally to find out why you are having symptoms, like chest pain, that could mean heart problems. Cardiac catheterization helps doctors to identify narrowed or clogged arteries of the heart, measure blood pressure within the heart, evaluate how well the heart valves and chambers function, check heart defects and evaluate an enlarged heart.
