Serial cardiopulmonary exercise testing in young patients after one-and-half ventricle repair and Fontan procedure: a comparative study
Authors' conclusion
These findings suggest that the 1.5VR may provide superior long-term functional outcomes than the Fontan procedure in patients with borderline HRV.
Study context
- Population
- Young patients with borderline hypoplastic RV after 1.5VR or univentricular heart after Fontan; Cardiopulmonary exercise tests (CPETs) September 2002–March 2024age at baseline 8.6 ± 2.6 years
- Participants
- 43 patients
- Exposure
- 1.5VR vs Fontan
- 1.5VRn = 10
- FSLVn = 21reference
- FSRVn = 12reference
- Outcome

Main finding
As reported in the abstract
Cardiorespiratory fitness and efficiency
- 1.5VR had higher cardiorespiratory fitness and efficiency vs FSLV and FSRV
Observational data: associations, not effects.
Further findings
Cardiorespiratory fitness and efficiency at first CPET · baseline
- No differences among the three groups
