About this study
Official title: Mechanisms of Dysfunction and the Influence of Exercise on Cardiac and Musculoskeletal Function in Children After the Fontan Procedure
Primary Objective: To determine if impairments in cardiac and musculoskeletal function and metabolism exist in Fontan children.
Secondary Objectives:
- To determine if impairments do exist, are they related to exercise capacity.
- To determine if a 12-week exercise training intervention improves cardiac and/or musculoskeletal metabolism.
Hypothesis: The investigators hypothesize that abnormalities in cardiac and skeletal function are evident, influence exercise capacity, and can be improved with exercise training.
Read the detailed description
This proposed research provides an interdisciplinary approach to understanding exercise intolerance by examining cardiac and musculoskeletal metabolism in a unique cohort of children with congenital heart disease. Study findings may more importantly lead to evidence-based exercise interventions that promote improvements in overall physical health, quality of life, and functional status for Fontan children. Furthermore, this pilot study will lead to the development of a novel research protocol which may be applied to larger Fontan and other congenital heart disease cohorts. This study will also provide preliminary data to develop and conduct a larger clinical research project.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Exercise ProgramOther
The Fontan cohort will subsequently complete a 12-week moderate intensity exercise intervention whereby individualized activity-based home interventions will be prescribed (i.e., sample activities: walking, jogging, swimming, cycling, soccer). More specifically, individualized weekly exercise programs for participants will be provided incorporating two specific exercise components.
| Study group | Role | What they receive |
|---|---|---|
| Fontan Patients | Experimental | Fontan patients who are monitored at the Hospital for Sick Children (SickKids) will undergo an exercise program Receives: Other: Exercise Program |
| Healthy Controls | No intervention | Healthy age-matched adolescents |
What is being measured
The primary outcome is the main question the study is designed to answer.
Cardiac and skeletal function and metabolism
Blood oxygen level dependent functional magnetic resonance imaging (BOLD fMRI), and 31P-MRS will allow for the precise measurement of cardiac and musculoskeletal function, circulatory perfusion and vascular reactivity, and aerobic and anaerobic metabolism, respectively. Cardiac function will be examined via MRI and exercise echocardiography.
Measured: 1 day

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Exercise Program in people with Congenital Heart Disease, run by The Hospital for Sick Children at 1 site in Canada.
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 7 inclusion and 15 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: stopped early, as of the sponsor's last update on 1 Feb 2016. 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 Canada. 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.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: Feasibility issues). Results are not available in the source record.
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?
Cardiac and skeletal function and metabolism (time frame: 1 day). 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 1 Feb 2016.
