摘要

Patent Ductus Arteriosus (PDA) is a frequent congenital heart defect in preterm newborns. Still, the assessment of hemodynamic significance is not obvious. In the presented pilot study the usefulness of phonocardiography in assessing the hemodynamics of the PDA was investigated. Nineteen infants have been examined, eleven with hemodynamically significant PDA verified by echocardiography. Four neonates have been measured daily until the clinically verified closure of the PDA occurred. Murmur was found in case of two infants with PDA. A cross-correlation based method was developed for analysis and comparison of heart sounds from records before and after the closure of the PDA. The splitting of the second heart sound might be related to the closure.
