  • To provide a new tool for improved diagnostic accuracy of these heart murmurs.

Main Methods:

  • Development of a novel auscultation device.
  • Utilizing the principle of sound conduction through a closed air system.
  • Application of the technique for listening to aortopulmonary shunt murmurs.

Main Results:

  • Successful demonstration of a new technique for auscultating aortopulmonary shunt murmurs.
  • The method leverages sound conduction principles for enhanced auditory signal transmission.
  • The described technique offers a novel approach to heart murmur auscultation.

Conclusions:

  • A novel technique for auscultating aortopulmonary shunt murmurs has been described.
  • The method utilizes sound conduction via a closed air system.
  • This innovation may enhance the diagnostic capabilities in pediatric cardiology.
