About this study

Official title: Improving Care for Children With Congenital Heart Disease by Cardiovascular Biomarker Profiling and Advanced Non-invasive Cardiac Imaging Techniques.

Establish a cardiovascular biomarker profile to help screening for congenital heart disease in infants and children as well as use non-invasive cardiac imaging in combination with such profiling to better predict the need for future cardiac interventions such as open heart surgery or cardiac catheter intervention in selected types of with congenital heart disease.

Read the detailed description

Analysing circulating cardiovascular biomarkers using blood samples should improve identification of congenital heart disease in newborns, in particular for those needing future cardiac interventions.

Comparing such biomarker profiles and non-invasive cardiac imaging results over time in infants and children should lead to better understanding of the complex cardiovascular remodelling processes in common congenital heart lesions, such as atrial or ventricular septal defects. This in turn should lead to an improved risk factor assessment model to guide treatment decisions in children with congenital heart disease in the foreseeable future.

To test our hypothesis, that cardiovascular biomarker profiling and non-invasive cardiac imaging findings in infants and children with congenital heart disease, differs from healthy controls, we will assess controls at enrolment and follow cases with predefined congenital heart disease lesions over a maximum of three years or up till one year after open heart surgery / cardiac catheter intervention to correct such lesions.

Infants and children resident in designated healthcare regions of Sweden will be invited to participate after study advertisement. Written informed consent will be obtained from legal guardians and assent will be sought from children who can communicate verbally with the dedicated paediatric research team.

Healthy subjects 0-17 years at enrolment will undergo i.e. standard electrocardiogram (ECG), echocardiography and blood sampling to evaluate the heart's anatomy and function and to obtain samples for subsequent blood-based biomarker analyses.

Additionally, saliva may be sampled and/or neonatal blood samples from national biobank storage will be retrieved for comparison with cardiovascular biomarker profiles in these controls if available.

To evaluate these cardiovascular assessments in predefined age groups, a subgroup of these participating subjects will be asked to complete additional cardiac magnetic resonance imaging based on study protocols.

Incidental findings of congenital heart disease will be followed up according to standard care protocols in designated paediatric cardiology clinics throughout the participating healthcare regions in Sweden.

A subgroup of cases with congenital heart disease that lead to pulmonary over-circulation, such as atrial and ventricular septal defects, partial anomalous pulmonary venous drainage, aorto-pulmonary windows and patent ductus arteriosus, will be asked to participate if the lesion has not been treated by open heart surgery or cardiac catheter interventions at enrolment.

Subjects with these predefined types of congenital heart disease aged 0-17 years at enrolment will undergo standard electrocardiograms (ECG), echocardiography and blood sampling to assess biomarkers at baseline and at 6-12 month follow-up intervals in dedicated paediatric cardiology clinics over a maximum period of three years.

Saliva samples and/or cardiovascular tissue obtained during open heart surgery may also be analysed for studied cardiovascular biomarkers. Additionally, neonatal blood samples from national biobank storage will be retrieved for comparison with current biomarker profiles if available.

For those congenital heart disease cases referred for open heart surgery or cardiac catheter intervention to correct the congenital heart lesion based on standard care assessment decisions during the study period, follow-up will end one year after such intervention. To evaluate cardiovascular assessments in predefined age groups, a subgroup of participating cases will be asked to complete additional cardiac magnetic resonance imaging based on study protocols.

Prospective evaluation of developed blood-based biomarkers assays and novel cardiac imaging biomarkers of heart function in infants and children will be further assessed to evaluate the feasibility of these methods to timely and precisely identify newborns with congenital heart disease by combined blood-based biomarker analyses and to assess whether newly identified functional parameters on heart function would be suitable to guide clinical risk-assessment and decision-making processes in terms of type and timing of cardiac interventions . These imaging biomarkers will, for example, evaluate the usefulness of measuring kinetic energy within the left ventricle of the heart in children with congenital heart disease based on magnetic resonance and echocardiography methods.

What is being measured

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

  1. Screening for congenital heart disease in newborns using circulating biomarkers in blood samples

    Results will be based on circulating biomarker analysis in infants using dried blood spot samples to improve detection of congenital heart disease. Results in normal controls will be compared to predefined congenital heart disease lesions and results expressed in ng/l using cardiovascular biomarkers such as NT-proBNP and IL1RL1 (ST2).

    Measured: 3 years

Secondary outcomes (3)
  1. Circulating cardiovascular protein biomarker profiling in infants and children with predefined congenital heart disease lesions vs normal controls using blood samples.

    Circulating biomarker profiling results will be expressed in 'NPX' units (Normalized Protein eXpression concentrations from proximity extension assay analyses of protein concentrations in blood samples using O-link's 'Target 96 cardiovascular III' panel, link: https://www.olink.com/products/cvd-iii-panel/)

    Measured: 3 years

  2. Measurement of cardiac magnetic resonance 4-dimensional flows to estimate e.g. 'kinetic energy' supported by advanced echocardiography in normal controls vs predefined lesions of congenital heart disease

    Results will be based on cardiac magnetic resonance 4D flow and supported by advanced echocardiographic assessments and expressed as kinetic energy (milli Joule) to assess for normal and abnormal patterns of cardiac function.

    Measured: 3 years

  3. Time from diagnosis to open-heart surgery or cardiac catheter intervention in predefined congenital heart disease lesions

    Number of days from date of diagnosis of predefined congenital heart disease lesion until date of open-heart surgery or cardiac catheter intervention to treat lesion

    Measured: 3 years

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Screening for congenital heart disease in newborns using circulating biomarkers in blood samples (time frame: 3 years). 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 8 May 2026.
