About this study

Official title: Artificial Intelligence in New Cardiac MR Markers for Congenital Heart Disease -Improving the Assessment, Monitoring and Prediction in Children

The goal of this study is to investigate children with aortic and pulmonary valve disease treated or untreated longitudinally. Established CMR measures with additional newly developped, promising, highly refined and clinically applicable quantitative imaging biomarkers, will be utilized as compared to the conventional CMR estimates.

The main question[s] it aims to answer are:

Read more
  • [question 1]To evaluate risk stratification for surgery and intervention of the aortic- and pulmonary valve
  • [question 2]Investigate the cardiac and vascular hemodynamic and morphological changes before and after interventional or surgical treatment of the aortic- and pulmonary valve at short and long term.

Participants will undergo cardiac MRI before and after interventional or surgical treatment of the aortic or pulmonary valve Researchers will compare MRI data to an age matched control group established at the department in another study.

Read the detailed description

Background:

An increasing number of children with complex congenital heart disease (CHD) are today treated and survive into adulthood. They are in need of a lifelong surveillance for cardiovascular complications and an individualised treatment.

In paediatric aortic and pulmonary valve disease, the long-term complications are related to valvular dysfunction with myocardial fibrosis and ventricular dysfunction as a result of longstanding volume or pressure overload. Many patients will need surgery or interventional treatment already in childhood, where the optimal timing of the intervention is crucial, since early treatment may prevent irreversible injury to the heart.

Moreover, to enable detection of recurrent or new problems early, a long-term diagnostic follow-up is needed where cardiovascular magnetic resonance (CMR) has become important for a serial reproducible assessment of morphology, function and recently advanced methods for flow and tissue characterisation. Still the the clinical decision of the perfect time-point and type of treatment for a child, may be difficult in many cases, and better measures are needed.

Aim:

This project will investigate children with aortic and pulmonary valve disease treated or untreated longitudinally using established CMR measures with additional newly developed, promising, highly refined and clinically applicable quantitative imaging biomarkers, as compared to the conventional CMR estimates. Investigators aim to evaluate risk stratification and investigate the haemodynamic and morphological changes as well as physical capacity before and after interventional or surgical treatment at short and long term.

CMR will be analysed for established imaging biomarkers as well as the potential value of new data-driven computer tools searching for new information in the CMR images i.e. shape/texture analysis of tissue change, regional haemodynamics, blood flow in relation to metallic implants and evaluation of myocardial deformation over time.

CMR measures will be compared to data from echocardiography, catheterization and serological markers.

Clinical importance:

If the new refined CMR biomarkers can reveal improved disease characterisation, they may reveal feasible in aiding the clinical decision making to optimise timing of intervention and predicting long term complications. This could contribute to individualise the treatment and improve health in children with CHD. The study may lead to improved patient care and use of socio-economical resources.

What is being measured

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

  1. CMR measures

    Measurement by CMR of changes in ventricular function, remodelling, tissue characterisation and advanced four dimensional flow (4D-flow) measurements after surgery or intervention

    Measured: Before and after 6 months, 1 year and up to 3 years after intervention or surgery

  2. Physical capacity

    Measurement of physical capacity after surgery or intervention, by cardiopulmonary exercise testing (CPET)

    Measured: Before and after 6 months, 1 year and up to 3 years after intervention or surgery

Secondary outcomes (1)
  1. CMR derived flow measurements near metallic implants, stents

    Refined measurements of CMR derived 4D-flow measurements near metallic implants, stents

    Measured: after 6 months, 1 year and up to 3 years after intervention

Questions about this trial

What is this clinical trial studying?

An observational study of Aortic Valve Disease and Pulmonary Valve Disease, run by Sahlgrenska University Hospital at 1 site in Sweden.

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 2 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: enrolling by invitation, as of the sponsor's last update on 15 May 2025. 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 Sweden. 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?

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?

CMR measures (time frame: Before and after 6 months, 1 year and up to 3 years after intervention or surgery). The study lists 2 primary outcomes in all. 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 15 May 2025.
