Doppler echocardiographic assessment of normal and malfunctioning mitral valve prostheses
The obstruction inherent to prosthetic valves leads to an increase in the velocity of blood flow across the prostheses, which can be detected by Doppler technique and the time profile of which can be characterized by various parameters. Thereby, values of normal functioning prostheses can be evaluated with the aid of which malfunctions may be detected and assessed. This investigation deals with the use of this method as applied to functional assessment of mechanical and biological mitral valve prostheses.
