Abstract
Ventricle septal defects (VSDs) are an important form of congenital heart disease. This study presents a new approach to VSD size estimation based on the discrete wavelet transform and artificial neural network classification of heart sounds. Heart sounds was recorded for 20 children with a VSD aged 19 ± 12 months when visiting the pediatric heart clinic of Shaheed Modarres Hospital in Tehran. The detection system was trained using 70 percent of the data and evaluated using the remaining 30%. It was found to be 96.6 percent accurate for small-size VSD (dhole<0.3daorta) and 93.3 percent accurate for large-size VSD (dhole>0.7daorta). Our results suggest that this approach may offer clinical utility in detecting and classifying VSDs in children.
