Primary Outcome(s)
Secondary Objective: Improvement in cardiovascular performance as measured by exercise test, cardiac MRI, Borg dyspnoea index and echo.
Main Objective: To demonstrate the safety of oral Bosentan therapy in patients with a Fontan circulation. The primary endpoint will be lack of clinically significant adverse events over the 6 month follow up period. Specifically we will look for evidence of hepatic dysfunction, haematological dysfunction and renal dysfunction. Patients will be assessed for symtomatic deterioration.

The primary endpoint will be lack of clinically significant adverse events over the 6 month follow up period. Specifically the study will look for evidence of hepatic dysfunction, haematological dysfunction and renal dysfunction. Patients will be assessed for symptomatic deterioration.
