ABSTRACT

The authors present 6 cases of calcified aortic valves, removed from patients during aortic valve replacement, which underwent photodebridement with CO2 laser. Radiographic, photografic weight and histopathological studies have shown extensive debridement, and the valves showing improved morphology and function. The advantages of the procedure made concerning valve replacement and clinical application is foreseen for the method.
