NCT ID NCT07376785
First seen Jan 31, 2026 · Last updated Jun 23, 2026 · Updated 19 times
Summary
This study tests a smartphone app called ausculto™ that records and analyzes heart sounds to detect congenital heart disease. Researchers will record heart sounds from 220 people aged 6 and older who have had recent echocardiograms. The goal is to see if the app can accurately tell the difference between normal heart sounds, innocent murmurs, and murmurs caused by congenital heart disease.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Smartphone app (ausculto™) that analyzes heart sounds
What this could lead to
If successful, this could provide a simple, low-cost way to screen for congenital heart disease using just a smartphone, making detection easier in places with limited access to specialists.
What could go wrong
This is an early observational study with only 220 participants. The app may not be accurate enough to replace standard tests like echocardiography, and results may not apply to all age groups or types of heart disease.
