Trial summary

This is a prospective, school-based, cluster-randomized controlled trial conducted in Qinghai Province, China. The study will evaluate whether artificial intelligence (AI) can help primary care physicians identify congenital heart disease (CHD) during large-scale screening of children and adolescents.

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 0 to 18 years
  • All sexes
  • Healthy volunteers accepted
  • Child, Adult

Who may be able to join

  • Children and adolescents aged 0-18 years who are enrolled in a participating school in Qinghai Province and are eligible for the school-based congenital heart disease screening program.
  • Written informed consent provided by the parent or legal guardian, or ethics-approved electronic informed consent, with participant assent obtained when applicable.
  • Ability to undergo the protocol-specified cardiac auscultation, heart-sound recording, and echocardiographic assessment.
  • Participant and/or parent or legal guardian is willing to provide the required medical history and, if referral is recommended, follow-up information.

Who cannot join

  • Inability to cooperate with cardiac auscultation, heart-sound recording, or echocardiography, when the required procedure cannot be completed after reasonable attempts.
  • Known congenital heart disease previously treated with catheter-based intervention or cardiac surgery, when the primary endpoint is not applicable under the protocol.
  • Any condition that prevents completion of the required study procedures or prevents obtaining an interpretable protocol-specified echocardiographic assessment.
  • Informed consent or assent is not provided, or consent is withdrawn before completion of the study procedures.

About this study

Official title: A Prospective, School-Based, Cluster-Randomized Controlled Trial Comparing AI-Assisted Versus Independent Cardiac Auscultation by Primary Care Physicians for Detecting Congenital Heart Disease in Qinghai Province, China

This is a prospective, school-based, cluster-randomized controlled trial conducted in Qinghai Province, China. The study will evaluate whether artificial intelligence (AI) can help primary care physicians identify congenital heart disease (CHD) during large-scale screening of children and adolescents.

Eligible schools, rather than individual participants, will be randomly assigned to one of two screening approaches: independent cardiac auscultation by primary care physicians or AI-assisted cardiac auscultation. In both groups, primary care physicians will perform cardiac auscultation and record heart sounds. In the AI-assisted group, the physicians will also receive AI analysis of the recorded heart sounds to support their final screening decision.

Participants will undergo medical history collection, cardiac auscultation, heart-sound recording, and echocardiography. Echocardiography and expert review will serve as the reference standard. The primary outcome is the sensitivity of each screening approach for detecting CHD that may require clinical intervention or specialist management. The study will also assess detection of all CHD, referral completion, confirmed diagnoses after referral, and related screening outcomes.

What participants receive

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

  • AI-Assisted Cardiac AuscultationOther

    During the school-based screening visit, a trained primary care physician will perform standardized cardiac auscultation and record the participant's heart sounds. The recorded heart sounds will be analyzed by an artificial intelligence-assisted auscultation system, which will provide automated analysis and decision-support feedback to the physician. The physician will consider the AI output together with the clinical examination and make the final screening and referral decision. The AI output is not a definitive diagnosis and will not replace echocardiography or specialist evaluation. No medication, surgery, or other therapeutic treatment will be administered as part of this intervention.

    Measured: From enrollment to the end of treatment at 6 months

Secondary outcomes (5)
  1. Specificity for Detecting Congenital Heart Disease Requiring Clinical Intervention

    Measured: From enrollment to the end of treatment at 6 months

  2. Sensitivity for Detecting All Congenital Heart Disease

    Measured: From enrollment to the end of treatment at 6 months

  3. Positive Predictive Value for Detecting Congenital Heart Disease Requiring Clinical Intervention

    Measured: From enrollment to the end of treatment at 6 months

  4. Referral Completion Rate

    Measured: From the initial screening visit through completion of the protocol-specified referral follow-up at 9 months

  5. Confirmed Diagnosis Rate After Referral

    Measured: From the initial screening visit through completion of the protocol-specified referral follow-up at 9 months

Questions about this trial

What is this clinical trial studying?

A study testing AI-Assisted Cardiac Auscultation in people with Congenital Heart Disease (CHD) and Artifical Intelligence, run by Kun Sun at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 21 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Liudan Zhao (0086-18368407858, sjdyszld@sjtu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensitivity for Detecting Congenital Heart Disease Requiring Clinical Intervention (time frame: From enrollment to the end of treatment at 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Sep 2026.
