Cardiac Catheterization: A cardiac catheterization is performed to obtain information about congenital or acquired heart defects, measure oxygen concentration, determine cardiac output, or assess the status of the heart’s structures and chambers. It may be performed during an angio cardiogram to study the function of the heart or blood supply or to diagnose congenital anomalies or valvular disease. Therapeutic treatments may be done during the catheterization to repair the heart, open valves, or dilate arteries. In this procedure, a long, flexible catheter is passed into the heart through a large blood vessel, usually the femoral or brachial artery. However, with the miniaturization of medical devices, an alternative approach is to use the radial artery (trans radial catheterization). The pressure is measured as the catheter passes through each location, and blood specimens are taken in each area. A dye may also be injected. A team of physicians, nurses, and technicians per-form this procedure, which takes from 1 to 3 hours.…
