Cardiac catheterization (also called cardiac cath or coronary angiogram) is an invasive imaging procedure that allows your doctor to evaluate your heart function. Cardiac catheterization is used to:

• Evaluate or confirm the presence of coronary artery disease, valve disease or disease of the Aorta
• Evaluate heart muscle function
• Determine the need for further treatment (such as an interventional procedure or coronary artery bypass graft, or CABG surgery)
