What is a Cardiac Catheterization and Coronary Angiogram?
A cardiac catheterization is an invasive, non-surgical procedure done to study the arteries that bring blood to the heart muscle and to check the function of the main pumping chamber of your heart. During a cardiac catheterization, the cardiologist inserts a small, hollow tube (catheter), into an artery or vein, and then guides it into the heart using x-ray. The cardiologist injects contrast (x-ray dye) through the catheter to outline the arteries and to show any blockages or narrowings that may exist. The results of these tests will assist your doctor in making the diagnosis of Coronary Artery Disease (CAD). Most patients have little or no discomfort during a cardiac catheterization. However, you may feel a hot, flushing sensation for several seconds when the contrast is injected into the main pumping chamber of the heart. The nursing and medical staff will give you medication and reassurance throughout the procedure to ensure your comfort.
