Brief Summary

The purpose of this research study is to evaluate the impact of a telemedicine-based structured home exercise program on frailty and exercise capacity in individuals with Fontan heart physiology, demonstrate that a telemedicine exercise program reduces socioeconomic and geographic barriers to access to exercise training, and to explore the impact of a structured exercise program on markers of Fontan-associated liver disease.

Detailed Description

This study will require two in-person visits to the exercise physiology lab as well as virtual follow-up visits. Visit one will require participants to complete a cardiopulmonary exercise test (CPET), liver ultrasound, 6-minute walk, grip strength test, arm circumference measure, body composition analysis, anthropometrics measurement, surveys and a biomarker blood sample collection. The second in-person visit will require participants to complete a final cardiopulmonary exercise test, liver ultrasound, 6-minute walk, grip strength test and arm circumference, biomarker blood sample and final survey.

Primary Outcome Measures
NameTimeMethod
Change in Frailty score by the Fried frailty instrumentday 1 (baseline), week 26 (final visit)

The questionnaire evaluates five components of the frailty syndrome (weakness, slowness, shrinkage, exhaustion, and diminished physical activity). Sum of the components will have a possible score of 0-5: not frail (score 0), pre-frail (score 1-2), frail (score great or equal to 3), undetermined (missing component).

Secondary Outcome Measures
NameTimeMethod
Change in Patient-Reported Outcomes Measurement Information System (PROMIS) - 29day 1 (baseline), week 26 (final visit)

This survey has 29 items across the following domains: depression, anxiety, physical function, pain interference, fatigue, sleep disturbance, ability to participate in social roles and activities, cognitive function on a scale of 1 (worst) to 5 (best), and pain intensity (on a scale ranging from 0 (no pain) to 10 (worst pain imaginable).

Change in 6-minute walk distanceday 1 (baseline), week 26 (final visit)
Change in Aspartate Transferase (AST)day 1 (baseline), week 26 (final visit)

This is a blood sample.

Change in Alanine Aminotransferase (ALT)day 1 (baseline), week 26 (final visit)

This is a blood sample.

Change in plateletsday 1 (baseline), week 26 (final visit)

This is a blood sample.

Change in 7-day average step count over 6 month periodBaseline, 6 months
Change in peak oxygen consumptionday 1 (baseline), week 26 (final visit)

This is measured during a Cardiopulmonary Exercise Testing (CPET) test measured in milliliters per minute (mL/min).

Change in alpha fetoprotein (AFP)day 1 (baseline), week 26 (final visit)

This is a blood sample.

Change in oxygen consumption at anaerobic thresholdday 1 (baseline), week 26 (final visit)

This is measured during a CPET.

Change in Enhanced Liver Fibrosis (Elf) Score numberday 1 (baseline), week 26 (final visit)

This is a blood sample.

Change in liver stiffness measured by ultrasoundday 1 (baseline), week 26 (final visit)

This is measured during ultrasound, units meters per second (m/sec)

Change in Gamma-glutamyl Transferase (GGT)day 1 (baseline), week 26 (final visit)

This is a blood sample.
