Portable electronic stethoscope and machine-learning detection of heart valve disease

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study records heart sounds with two portable electronic stethoscopes (BPM Core and BeamO) and compares machine-learning algorithm predictions to clinicians' interpretations and echocardiogram results. Participants include 100 patients diagnosed with valvular heart disease and 25 healthy controls recruited at Queen Mary Hospital in Hong Kong. Each participant will undergo echocardiography (within the prior five years), an ECG using the BPM Core device, and auscultation recordings for algorithm analysis. The main outcome is diagnostic agreement and accuracy of the algorithms versus clinician readings and echocardiographic findings.
