Brief Summary

Congenital heart disease (CHD), the most common birth defect, is present in nearly 1% of the population. CHD patients are associated with intense resource utilization and premature death in adulthood. The risk of premature death is linked with reduced exercise capacity, a finding consistently noted in youth with CHD. Reduced exercise capacity in this population has also been associated with reduce physical activity and health-related quality of life. Cardiac rehabilitation (CR) in adults with acquired heart disease is an established secondary prevention strategy that improves exercise capacity. The investigators propose a prospective clinical trial of a home-based high intensity interval training (HIIT) program using a novel telemedicine-equipped video game-linked cycle ergometer (MedBIKE™) for 10 to 18 year olds with repaired moderate-complex CHD. The pilot study with the MedBIKE has shown promising results. The investigators now seek to study the efficacy of this program in a broader CHD population.

Outcome Measures

Primary Outcomes (1)

  • Exercise capacity in the change in VO2peak (mL/kg/min) measured through CPET testing

    CPET (Exercise Stress Test and Spirometry) will be done to measure the VO2peak (mL/kg/min) output of participants. A comparison will be done pre- and post-MedBIKE intervention, as well as 6 and 12-months post, to determine the change in overall VO2peak of participants. We will also evaluate changes in VE/VCO2, peak power output (W), and HRmax (maximum heart rate).

    Baseline, 1-week post-intervention, 6-months post-intervention, 12-months post-intervention

Secondary Outcomes (4)

  • Changes in physical activity, defined as time spent in moderate to vigorous physical activity (MVPA) and sedentary time, measured by wearing an accelerometer for 7-days prior and 7-days post MedBIKE intervention

    Baseline, 1-week post-intervention, 6-months post-intervention, 12-months post-intervention

  • Changes in Health-Related Quality of Life as measured using the TNO AZL Children's Quality of Life (TACQOL) questionnaire.

    Baseline, 1-week post-intervention, 6-months post-intervention, 12-months post-intervention

  • Changes in self efficacy towards physical activity measured on the Children's Self-Perceptions of Adequacy in and Predilection for Physical Activity (CSAPPA) scale.

    Baseline, 1-week post-intervention, 6-months post-intervention, 12-months post-intervention

  • Changes in endothelial function to determine arterial volume will be measured using an EndoPAT 2000 instrument.

    Baseline, 1-week post-intervention, 6-months post-intervention, 12-months post-intervention

Eligibility Criteria

Age10 Years - 18 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Children and adolescents aged 10-18 years
  • Repaired moderate-complex congenital heart disease

You may not qualify if:

  • Non-English speaking (thus limiting communication during the MedBIKE™ sessions)
  • Home environment cannot accommodate the MedBIKE™ system (space limitations)
  • Previous involvement in a cardiac rehab or exercise intervention program
  • Primary cardiologist has exercise restricted the participant or counsels against participation
  • Previous exercise stress test demonstrating sustained arrhythmias, ST segment elevation or depression greater than 3mm, an inappropriate rise in blood pressure (BP) (\<20 mmHg) or a systolic BP \>200 mmHg, or symptoms of chest pain or syncope
  • Resting arterial saturation \<85% or oxygen requirements
  • Moderate ventricular systolic dysfunction (or worse) at the most recent echocardiogram
  • History of chest pain on exertion
  • Unrepaired/unpalliated CHD
  • Arrhythmias in the last year (including supraventricular tachycardia, ventricular tachycardia, atrioventricular block (Mobitz II or worse))
  • New York Heart Association class II or worse symptoms
  • Active medical inter-current illness limiting ability to participate
  • Cognitive impairment limiting the communication needed for the HIIT program
  • Extracardiac or congenital abnormality limiting the participant's functional ability to exercise
