Mobile Screening

Summary:

The One Heart App is a telemedicine system to support local health providers to identify signs of congenital heart diseases (CHD) and reduce its late diagnosis in low resource settings. The One Heart App enables local health workers to inexpensively record and transmit heart sounds from children with signs of CHD to obtain consultation from specialists through mobile networks. The One Heart App aims to reduce morbidity and mortality associated with CHD by providing early screening that does not require a specialist.

Completed Work:

We developed early versions of One Heart App based on the first-hand observation of the late diagnosis of CHD and challenges associated early CHD screening in collaboration with Children’s HeartLink, a non-government organization based in Minnesota with the mission of improving access to high-quality heart care in underserved areas. The first version of the One Heart App system consisted an iOS-based mobile software application and a custom made digital stethoscope for recording of heart sounds. During outreach programs in county hospitals in Linxia and Huining, Gansu Province of China, we successfully collected digital heart sounds using the One Heart system. A trained cardiologist (Dr. Pyles) could differentiate 18 pathologic murmurs from one innocent murmur using signals collected by the One Heart system in comparison with standard auscultation and echocardiography. The results were presented at the American Heart Association Scientific Session in 2012 at Los Angeles, US.

After the pilot study in Gansu, China, we developed a second software application on an Android system (pre-alpha version) with additional telemedicine functions of communication via mobile network for remote consultation. In collaboration with Children’s HeartLink partner site in Kunming Medical University and First Affiliated Hospital (KMU), we participated in a screening program in Menghai County, Yunnan Province of China in December 2014. The KMU team screened 7,993 children for signs of CHD using standard auscultation.

We collected digital heart sounds from 149 children with suspected murmurs using the One Heart App.  Using echocardiography as the reference method, a trained cardiologist (Dr. Pyles) using the One Heart App found pathologic murmurs in 11 of 14 subjects with true CHD. Three missed were atrial septal defect called venous hum in two of three patients; likely related to respiratory artifact. Accuracy was 136/149 or 91% with 10 false positives. Positive predictive value was 52% and negative predictive value 98%. The results of this study have been published in Pediatric Cardiology.¹ 

In 2023, One Heart Health launched the Global Digital Heart Sounds Study with partners in Bolivia, Nigeria, Mongolia, and the United States which resulted in the collection and annotation of over 400 patients with suspected murmurs using the One Heart App. This research is ongoing and will benefit One Heart Health’s AI/ML research to enhance automatic murmur detection.
