Abstract EN
Experimental research results of hydrodynamic noise of pulsating flow through a bileaflet mechanical mitral valve are presented.
The pulsating flow of pure water corresponds to the diastolic mode of the cardiac rhythm heart.
The valve was located between the model of the left atrium and the model of the left ventricle of the heart.
A coordinate device, on which a block of miniature sensors of absolute pressure and pressure fluctuations was installed, was located inside the model of the left ventricle.
It is found that the hydrodynamic noise of the pulsating side jet of the semiclosed valve is higher than for the open valve.
The pressure fluctuation levels gradually decrease with the removal from the mitral valve.
It is established that at the second harmonic of the pulsating flow frequency, the spectral levels of the hydrodynamic noise of the semiclosed bileaflet mechanical mitral valve are almost 5 times higher than the open valve.
With the removal from the mitral valve, spectral levels of hydrodynamic noise are decreased, especially strongly at the frequency of the pulsating water flow and its higher harmonics.
