Abstract :
Discrete wavelet transform has been proposed for the diagnosis of paravalvular leakage(PVL) occurs after Mechanical Heart Valve(MHV) replacement. Mechanical heart sounds of 2 patients with PVL and 5 volunteers with normal MHV was recorded and analyzed with different wavelets. As a result, it is statically shown that Daubechies 2 wavelet function is suitable for diagnosis of PVL.
