Who can take part
AI summary
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for people aged 6 years or older who had a heart ultrasound (echocardiography) within 3 years. Their heart sounds will be recorded with a smartphone to test software that looks for inborn heart disease.
- Age
- 6 years and older
- Sex
- All sexes
- Disease stage
- People with a normal or an abnormal heart ultrasound result can join.
- Earlier treatment
- Must have had an echocardiography (heart ultrasound) within 3 years, during a normal hospital visit outside the research.
Main reasons for not taking part
- Active medical devices implanted in the chest or body, such as pacemakers and defibrillators
- Heart valve disease that is only non-congenital (not present from birth)

About the trial
What the trial wants to find out
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.
Read full original descriptionShow less
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.
The 2 groups in the trial
- Abnormal Echocardiography Diagnosis
Participants with abnormal echocardiography diagnosis within three years.
Treatment: Computer algorithms
- Normal Echocardiography Diagnosis
Participants with normal echocardiography diagnosis within three years.
Treatment: Computer algorithms
Questions to ask the study team
- How often do I need to come in, and for how long each time?
- Are travel costs paid?
- Can I keep my own doctor?
- What happens if I want to stop?
