Trial summary

The main objective of this study is to evaluate a machine learning model's ability to detect murmurs indicative of structural heart disease ("structural murmur") by analyzing phonocardiogram waveforms-and simultaneous electrocardiogram waveforms when available-in multiple auscultatory positions per subject.

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: 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.

Who may be able to join

  • 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

Who cannot join

  • 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

About this study

The main objective of this study is to evaluate a machine learning model's ability to detect murmurs indicative of structural heart disease ("structural murmur") by analyzing phonocardiogram waveforms-and simultaneous electrocardiogram waveforms when available-in multiple auscultatory positions per subject. Diagnosis of structural murmur will be confirmed by gold-standard echocardiography and reviewed by an expert panel of cardiologists.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Eko digital stethoscopesDevice

    Use of the Eko CORE 500 digital stethoscope and 3M Littmann CORE Digital Stethoscope to auscultate and record cardiac phonocardiogram and (when available) electrocardiogram waveforms, as well as heart sounds.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Primary outcome

    Evaluate a machine learning model's ability to detect murmurs indicative of structural heart disease ("structural murmur") by analyzing phonocardiogram waveforms-and simultaneous electrocardiogram waveforms when available-in multiple auscultatory positions per subject. Diagnosis of structural murmur will be confirmed by gold-standard echocardiography and review by an expert panel of cardiologists.

    Measured: 6 months
