Heart Valve Disease Classification Using Neural Network

Heart valve diseases such as aortic stenosis, mitral regurgitation, mitral stenosis and aortic regurgitation can be audible directly by stethoscope. Valve diseases are characterized by systolic murmur and diastolic murmur features. Segment heart sound wave into S1, S2 systolic murmur and diastolic murmur then segments features given to artificial neural network to classify disease. Instead of giving complete PCG wave to ANN give segments and test disease for those segment only then cumulative results of each segment will give final valve disease name. ANN is trained with 49 S1 components, 43 systolic segments consists of 15 of aortic stenosis and 11 of mitral regurgitation.37 diastolic segments used to classify mitral stenosis and aortic regurgitation. These ANN are giving 84.93 % accuracy for S1 test signals having 12 test segments. Systolic gives 88.73 % accuracy and diastolic gives 91.72 % accuracy.
