The hypothesis of this study is that participation in a formal cardiopulmonary rehabilitation program improves aerobic exercise capacity and quality of life over the medium term for patients with congenital heart disease with reduced exercise capacity. To test this hypothesis, subjects will be randomized to either receive a 12-week cardiopulmonary rehabilitation program or standard of care, with interval testing of aerobic capacity and other physiologic markers improved fitness, as well as assessment of quality of life.

Primary Outcome Measures:
  • Change in aerobic exercise capacity (peak VO2) [ Time Frame: Baseline to 3 months (primary) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change in quality of life measurement [ Time Frame: Baseline to 3 months (primary) ] [ Designated as safety issue: No ]

Other Outcome Measures:
  • Change in peak cardiac output and its components (SV/HR) [ Time Frame: Baseline to 3 months (primary) ] [ Designated as safety issue: No ]
  • Mechanism of change in peak VO2 [ Time Frame: Baseline to 3 months (primary) ] [ Designated as safety issue: No ]
    Cardiac output will be assessed and O2 delivery/extraction will be estimated to define mechanisms of improvement in exercise capacity.

  • Change in ventilatory efficiency [ Time Frame: Baseline to 3 months (primary) ] [ Designated as safety issue: No ]
  • Change in strength (dynamometry) [ Time Frame: Baseline to 3 months (primary) ] [ Designated as safety issue: No ]
  • Change in pulse wave velocity [ Time Frame: Baseline to 3 months ] [ Designated as safety issue: No ]
  • Change in circulating biomarkers [ Time Frame: Baseline to 3 months (primary) ] [ Designated as safety issue: No ]
  • Change in markers of pulse reflection [ Time Frame: Baseline to 3 months ] [ Designated as safety issue: No ]
  • Incidence of arrhythmia and other adverse events during cardiopulmonary rehabilitation [ Time Frame: Baseline to 3 months ] [ Designated as safety issue: Yes ]
  • Change in physical activity [ Time Frame: Baseline to 3 months ] [ Designated as safety issue: No ]
    Survey and accelerometry

  • Change in markers of ventricular function [ Time Frame: Baseline to 3 months ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: Cardiopulmonary rehabilitation
The subjects will attend 2 sessions each week for 12 weeks. Each session will be approximately 2 hours in duration, consisting of both exercise (aerobic and strength,~60 minutes) and education. In addition, subjects will be directed to participate in 3 weekly ~40 minute home exercise training sessions, personalized to their level of aerobic conditioning.
Other: Cardiopulmonary rehabilitation
See Arm Description
Standard of care
Subjects randomized to standard of care will not be enrolled in a rehabilitation program, but may receive any other clinically indicated exercise training or other intervention (e.g., an exercise prescription).
Other: Standard of care
See Arm Description
