What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled This study
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study is testing whether a machine learning algorithm can accurately detect heart murmurs that point to structural heart disease. Researchers will record heart sounds from 125 adults using two different digital stethoscopes and compare the algorithm's findings to standard echocardiograms. If the algorithm works well, it could help doctors identify heart problems more quickly and easily.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Eko CORE 500 and 3M Littmann CORE digital stethoscopes
What this could lead to
If successful, this could lead to a more accurate, non-invasive way to detect heart murmurs using digital stethoscopes, potentially reducing the need for unnecessary echocardiograms.
What could go wrong
This is a small, early-stage study (125 participants) focused on algorithm improvement, not a treatment. The algorithm may not perform well enough in real-world settings or across diverse patient groups.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Potential research subjects will be screened for eligibility from cardiology clinics, echocardiogram clinics, and inpatient areas. In order to be eligible, a patient must be 18+ years of age, have a documented history of structural heart disease, and has undergone an echocardiogram within the last 30 days. If a patient meets all of the specified inclusion criteria, and none of the specified exclusion criteria, the patient or their proxy will be approached to discuss participation in the study.

Ages

18 years and older

Inclusion Criteria: * 18+ years old * Patient or patient's legal healthcare proxy consents to participation * Documented history of SHD * Undergoing (or has undergone, within 30 days) a complete echocardiogram * Willing to have heart recordings done with two different electronic stethoscopes Exclusion Criteria: * Patient or proxy is unwilling/unable to give written informed consent * Unable to complete a complete echocardiogram, or none recent completed within the last 30 days * No documented history of SHD * Experiencing a known or suspected acute cardiac event * Mechanical ventricular support (such as ECMO, LVAD, RVAD, BiVAD, Impella, intra-aortic balloon pumps, TAH, VentrAssist, DuraHeart, HVAD, EVAHEART LVAS, HeartMate, Jarvik 2000) * Unwilling or unable to follow or complete study procedures
