Design outcomes

Primary

Measure	Time frame
The study aims to investigate whether there is a correlation between physical exercise capacity and the specific ventricle (left ventricle vs. right ventricle), the surgical method (fenestrated Fontan tunnel vs. non-fenestrated Fontan tunnel), the oxygen saturation level, regular physical activity vs. no physical activity, the presence of cardiac arrhythmias, or treatment with or without PDE5 inhibitors/endothelin receptor antagonists.	—
