Background: In Fontans, exercise tolerance is poorer compared to their healthy peers. Higher represents a strong predictor for mortality and morbidity in these patients. Cardiac rehabilitation programs have been shown to improve cardiopulmonary function in Fontans. More habitual physical activity should therefore lead to a better exercise tolerance.
Methods: We performed cardiopulmonary exercise testing in 24 Fontan patients who had engaged in physical activity for a minimum of 3 h per week over their lifetime. As a control we performed cardiopulmonary exercise testing in 20 Fontan patients who had undertaken no physical activity or <3 h per week in the past.
Results: A total of 44 Fontan patients was included (mean age 18.1 years). The mean parameters measured at peak exercise differed significantly between the active and inactive group (peak oxygen uptake [ ] of 34.0 vs. 25.0 ml/min/kg, peak heart rate (HR) of 169.8/min vs. 139.8/min). Even though the Opulse and the EF did not differ significantly between both groups, N-Terminal-Pro-B-Type Natriuretic Peptide (NT-pro BNP) was significantly higher in the inactive group. The two groups did not differ with respect to their cardiac function determined by magnetic resonance imaging (MRI). was positively correlated with hours of sports performed by Fontans.
Conclusions: and maximum HR were significantly higher in Fontans who had been physically active compared to those who had been inactive. The values reported in this study were higher than in other studies and reached normal values for for most Fontans in the physically active group. The positive correlation between and physical activity is an indicator of the importance of incorporating physical exercise programs into the treatment of Fontan patients.

Systemic-to-pulmonary collaterals (SPCs) are common in congenital heart disease (CHD). Particularly in single ventricle anatomy and Fontan circulation, SPC can both complicate the postoperative course and lead to clinical deterioration in the long term. The treatment of SPC is controversial.

Background: The discussion of Fontan fenestration is difficult because many institutions have different strategies over time. In our institute, we performed a non-fenestrated Fontan procedure for single-ventricular physiology as our definitive strategy.
Methods: Between August 1999 and December 2007, 72 consecutive patients with single-ventricle physiology underwent extracardiac total cavopulmonary connection without fenestration as our definitive strategy.

Background: The primary treatment for hypoplastic left heart syndrome (HLHS) is the Fontan pathway, which entails performing the Glenn procedure. We hypothesized that the superior vena cava in patients with HLHS was short. As the length of the superior vena cava influences the Glenn procedure, we compared its length between patients with HLHS and those with other congenital heart diseases.

Background: Single-ventricle cardiac defects (SVCDs) are among of the most health care resource-intensive congenital diseases. Although SVCDs are traditionally palliated using the Norwood pathway, in the last 2 decades select programs have used the hybrid strategy, which redistributes the operative and interstage risks. This study sought to characterize resource use for a cohort of patients with hybrid-palliated SVCD.

Background And Objective: Cardiovascular magnetic resonance (CMR) is a routine cross-sectional imaging modality in adults with congenital heart disease. Developing CMR techniques and the knowledge that CMR is well suited to assess long-term complications and to provide prognostic information for single ventricle (SV) patients makes CMR the ideal assessment tool for this patient cohort. Nevertheless, many of the techniques have not yet been incorporated into day-to-day practice.
