Smartphone-based screening for aortic valve stenosis

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 explores whether a smartphone-based signal acquisition method can help screen for aortic valve stenosis. Participants include adults with moderate to severe disease and those without significant valvular disease, using routine echocardiography as a reference. The study focuses on leveraging artificial intelligence and accessible technology to enable broad, low-cost screening outside traditional imaging settings. Data will be collected from smartphone signals and analyzed to see if they can indicate the presence of clinically relevant valve narrowing. No interventional procedures are involved; the aim is to assess feasibility and potential diagnostic value in real-world clinical practice.

Why it matters

* Documented echocardiography as part of routine clinical practice no older than 90 days
* Patient age ≥ 18 years
* Provided written informed consent

Inclusion criteria for group II:

* No significant VHD, valvular prosthesis, pacemaker or congenital heart defect
* Documented echocardiography as part of routine clinical practice no older than 90 days
