Enabling pediatricians to identify innocent heart murmurs


StethAid brings intelligent heart murmur identification from specialist (pediatric cardiology) offices to the primary care offices. Our digital auscultation platform enables easy recording and cloud-based storage and sharing of heart sounds using a mobile app. Embedded in the app are clinically validated artificial intelligent (AI) algorithms that help identify innocent Still’s murmur with cardiologist-level accuracy at the point of recording.    

In the United States, approximately half a million children with innocent Still’s murmurs are referred to pediatric cardiologists per year. These referrals and associated tests are medically unnecessary and avoidable. As a decision support system, StethAid helps reduce such referrals and avoid the anxiety, inconvenience, and cost associated with them.   



AusculTech Dx is a Children’s National Medical Center spin-off working on translating and commercializing computerized auscultation analysis research. Entrepreneurs and inventors, who have translated novel technologies developed in academia to FDA-cleared products, make up the founding team.
