About this study

The goal of this clinical trial is to learn if a specific type of exercise training (high intensity interval training) can improve exercise capacity in people with a congenital heart defect that required the creation of a new connection between the right ventricle and pulmonary artery. This includes people with a truncus arteriosus, pulmonary atresia with a ventricular septal defect or severe tetralogy of Fallot. This study focuses on people aged 12 to 45 years. The main questions it aims to answer are:

  • Can a 12-week home-based high intensity interval exercise training program increase the exercise capacity?
  • Can factors that predict whether or not the exercise training program can increase the exercise capacity in specific people be identified?

Researchers will compare the results from the intervention group to the control group. Participants will be assigned to one of these two groups at inclusion. The control group will also receive the intervention, after the control period.

Participants will:

  • Participate in a 12-week home-based exercise training program (3x30 minutes a week, digitally supervised);
  • Attend 2 or 3 study visits (which partially is standard care) (2 visits for the intervention group, 3 visits for the control group);
  • Each study visit includes: echocardiography, magnetic resonance imaging (MRI) of the heart, cardiopulmonary exercise testing (CPET), blood and feces sampling, and questionnaires on quality of life and physical activity.

What participants receive

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

  • High intensity interval trainingBehavioural

    A 12-week high intensity interval training program, with 30 minutes of exercise three times a week. The trainings can be completed at home and will be digitally supervised.

Study groups in NCT06771687
Study groupRoleWhat they receive
InterventionExperimentalThis arm receives the 12-week exercise intervention, with a study visit before and after the intervention.
Receives: Behavioral: High intensity interval training
ControlNo interventionThis arm starts with a 12-week control period, after which the participants will also receive the 12-week exercise intervention. Participants will have a study visit before and after the control period and after the intervention. For the primary outcome parameter, only the control period will be used to compare to the intervention. For the secondary outcome parameters (predictors for response), also the intervention period of the control group will be used.

Questions about this trial

What is this clinical trial studying?

A study testing High intensity interval training in people with Congenital Heart Disease and Truncus Arteriosus, run by Erasmus Medical Center at 2 sites in Netherlands.

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 8 inclusion and 10 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: looking for participants now, as of the sponsor's last update on 21 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Netherlands. 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 Anouk S Moerdijk, MD (+31107036264, a.moerdijk@erasmusmc.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Peak oxygen consumption (time frame: At baseline, week 14, week 27 (control arm only) and 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06771687, which also lists 1 linked publication.

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 Jan 2026.
