What this trial studies

This clinical trial evaluates the effectiveness of a home-based high intensity interval training (HIIT) program using a telemedicine-enabled cycle ergometer called MedBIKE™ for children and adolescents aged 10-18 with repaired moderate-complex congenital heart disease (CHD). The study aims to improve exercise capacity, physical activity levels, and overall quality of life by engaging participants in an eight-week HIIT regimen. The trial will assess various outcomes, including exercise capacity, sedentary time, and endothelial function, with follow-up evaluations extending up to one year post-intervention. This approach addresses the limited data on sustained exercise interventions in the pediatric CHD population.

Who should consider this trial

Good fit: Ideal candidates are children and adolescents aged 10-18 years who have repaired moderate-complex congenital heart disease.

Not a fit: Patients who may not benefit include those with severe exercise restrictions, unrepaired congenital heart defects, or significant cardiac dysfunction.

Why it matters

Potential benefit: If successful, this program could significantly enhance exercise capacity and quality of life for youth with congenital heart disease.

How similar studies have performed: Previous studies have shown promising results for exercise interventions in pediatric populations, but this specific approach using MedBIKE™ is novel.

Eligibility criteria

* 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
