Cardiac Catheterization is a procedure to evaluate blood flow to the heart, test the pumping ability of the heart and study various heart structures. Cardiac catheterization can be done to confirm the presence of coronary artery disease and valve disease. It can also help determine the need for further treatment such as coronary stent, bypass, surgery or valve replacement.
During this procedure, a short tube called a sheath is placed into your leg or arm artery. A long, thin tube called a catheter is passed through the sheath and guided to the heart arteries while the physician watches on a video screen. X-ray dye is then injected through the catheter and into the heart arteries, and x-ray movies are created as the dye flows through the arteries. A different catheter may be guided to the heart to determine pressures within the chambers and to study the valves. You can expect to spend 3-6 hours recovering in the observation area after a heart catheterization procedure.
