Smartphone Phonocardiography Trial Opens: Can the ausculto™ Algorithm Detect Congenital Heart Disease Through a Phone Microphone?

A University of Hong Kong-sponsored trial is evaluating ausculto™, a smartphone-based phonocardiography algorithm, for its ability to distinguish congenital heart disease murmurs from innocent heart sounds in patients aged six and older. The 220-participant observational study, enrolling by invitation in Hong Kong, will also generate a rigorously annotated heart sound database to underpin future cardiac screening technologies. Clinicians in paediatric cardiology and digital health should monitor this trial closely as results are anticipated in late 2026.
