Study characteristics
Methods Aim of study: compare the effects of standard of care to SOC plus participant in a typical clinical CR program in ACHD.
Study design: RCT
No. of centres: 4
Country: USA
Participants N randomised total: 33; intervention: 18; comparator: 15
Diagnosis of ConHD total: 33; intervention: 18; comparator: 15
Severity of condition:
  • intervention: mild = 0; moderate to severe = 18

  • comparator: mild = 0; moderate to severe = 5


N analysed total: 28; intervention: 13; comparator: 15
(5 did not receive intervention due to geographical reasons)
Age (mean ± SD) total: 41.1 (12.1); intervention: 47.5 (9.0); comparator: 35.7 (11.9)
Percentage male total: 50; intervention: 53.9; comparator: 46.7
Inclusion criteria: age > 16 years, ability to provide informed consent, ability and willingness to participate in a 12‐week CR program and repeated cardiopulmonary exercise testing (CPET), impaired aerobic capacity defined as peak _VO2 < 80% predicted on baseline exercise test, baseline resting oxygen saturation (sO2%) > 92%, and CHD of at least moderate complexity.
Exclusion criteria: cardiac intervention (catheterization or surgery) within the prior 6 months or planned cardiac intervention within 12 months of enrolment, formal CR within 24 months prior to enrolment, current or recent pregnancy (delivery < 90 days prior to enrolment), pregnancy planned within 12 months, active heart failure or hospitalization or other major clinical change during the 30 days prior to enrolment, and other recent or planned events expected to substantially impact exercise capacity.
