Cardiac catheterization is a procedure that helps your doctor diagnose or treat heart conditions. It is sometimes called heart catheterization, heart cath, or cardiac cath. A catheter (thin tube) allows your doctor to perform various tests and treatments by visualizing the blood vessels of your heart.
