HIIT in Youth With Congenital Heart Disease (MedBIKE)

Congenital Heart Disease | Pediatric ALL

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.

* Repaired moderate-complex congenital heart disease

Exclusion Criteria:

* 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
