Can Smartphones Listen to Your Heart? A Performance Study on Detecting Inborn Heart Diseases in Your Heart Sounds

Smartphone-Based Use of Phonocardiography for Detection of Congenital Heart Disease: Diagnostic Performance Study

This observational study aims to assess the performance of the software called ausculto™. ausculto™ is a collection of computer algorithms that intend to analyse heart sounds recorded from the built-in microphone of a smartphone for abnormal sounds.

Participants will have their heart sounds recorded during their normal attendance at the hospitals after consenting to participate in this study.

Researchers will manually annotate the recorded heart sounds to create a database for use in future training and testing of artificial intelligence (AI) intended for medical uses.

Inclusion Criteria:

• Age: ≥ 6 years
• Have undergone echocardiography within 3 years at their normal non-research hospital attendance

Exclusion Criteria:

• Implanted active medical devices in the torso, such as pacemakers and defibrillators
• Have purely non-congenital valvular heart disease
