Abstract

Congenital Heart Disease(CHD) complicated with Pulmonary Artery Hypertension(CHD-PAH) is one of the more harmful CHD-related complications. The objective of this paper was to develop a algorithm to study CHD-PAH from the perspective of heart sounds. This could enable adolescents to be detected and treated early without the need for expensive equipment or specialist skills. For this purpose an algorithm was designed. According to the pathological signs of CHDPAH in terms of heart sounds, i.e., it is mainly reflected in the hyperactive P2 of pulmonary valve component and the presence of A2 and P2 splitting. An image generator was used to feed the Choi-Williams distribution features of the Second Heart Sound(S2) into a convolutional neural network for training. A accuracy of 94.1% and a sensitivity of 94.9% were achieved using novel signal processing techniques and an ensemble of neural networks as classifier.
