Cardiac catheterization (cardiac cath, heart cath, or coronary angiography) is a procedure to examine how well blood is flowing to your heart. A catheter, similar to an IV, is inserted into your wrist or groin and follows the path that leads to your heart. When the catheter reaches your heart contrast dye is injected through the catheter to look for narrowing or blockage in the vessel. If a narrowing or blockage is found it is often treated with a balloon and/or stent during the same procedure. Ballooning (Angioplasty) uses a tiny balloon to open blocked arteries. Stenting is the insertion of a tiny wire mesh tube into an artery to hold it open.
