Who this trial is looking for
This trial is looking for children aged 10-17 with Fontan Circulation. Participants will take part in a home exercise program for 6 months while wearing a physical activity tracker for a year.
Are You a Good Fit for This Trial?
You may be able to join if
I have Fontan Circulation.
I am a girl aged 11 or older and have a negative urine pregnancy test.
I can follow the study procedures.
I speak English and have an English-speaking parent or guardian.
I can perform the exercise stress test and my peak VO2 is less than 80% of the normal range.
You may not be able to join if
I cannot complete an exercise stress test.
I have uncontrolled lymphatic disorders.
I have uncontrolled noncardiac conditions.
I have exercise-induced or uncontrolled arrhythmias.
I have a pacemaker or internal cardiac defibrillator.
My peak VO2 is less than 45% of the normal range.
I have had or am being considered for a heart transplant.
I am pregnant or breastfeeding.

The goal of this randomized control trial is to learn about physical fitness and exercise habits in children aged 10-17 with the Fontan Circulation through a home-based, digital exercise intervention. The main questions it aims to answer are:
* Does a home-based, digital intervention increase physical activity (PA) in youth with the FC compared to enhanced usual care?
* Does a home-based, digital…
The goal of this randomized control trial is to learn about physical fitness and exercise habits in children aged 10-17 with the Fontan Circulation through a home-based, digital exercise intervention. The main questions it aims to answer are:
* Does a home-based, digital intervention increase physical activity (PA) in youth with the FC compared to enhanced usual care?
* Does a home-based, digital intervention increase physical fitness in youth with the FC compared to enhanced usual care?
* Do multi-level factors (medical, neurodevelopmental, sociodemographic, neighborhood) impact the effectiveness of the digital intervention?
Researchers will compare participants in the enhanced usual care arm to those in the exercise intervention arm to see if the digital intervention is effective.
All participants will wear a PA tracker for 12 months and complete testing at baseline, 6 months, and 12 months.
In addition, participants in the exercise intervention arm will complete a 6-month exercise intervention with the following components:
* aerobic exercise
* resistance exercise
* engagement strategies
