Official title
Smartphone-Based Use of Phonocardiography for Detection of Congenital Heart Disease: Diagnostic Performance Study
Overview
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.
Interventions
- Diagnostic test Computer algorithms
Collection of lightweight computer algorithms called ausculto™ that is designed to perform real-time heart sound analysis to detect heart murmur.
Primary outcome measures
- Differentiation of Murmurs Associated with Congenital Heart Disease from Normal Heart Sounds and Innocent Murmurs in Heart Sound Recordings [Time frame: Day 0]
Secondary outcome measures (2)
- Differentiation of Murmurs Associated with Congenital Heart Disease from Normal Heart Sounds and Innocent Murmurs in Heart Sound Recordings [Time frame: Day 0]
- Number of Adverse Events Reported by Participants or Child Participants' Parent/Legal Guardian During and at the End of Heart Sound Recording That are Determined to be Caused by This Study [Time frame: Day 0]
Eligibility criteria
