1 Can you describe a few instances that might cause a case of tetralogy of Fallot to go into congestive cardiac failure, even though this is an unlikely occurrence? Please explain how this happens.

2 Is a single ventricle disease associated with any syndrome? If so, what is its name and what are its characteristics?
