In brief: Not very likely
In general, tetralogy of fallot has a 3% chance of recurrence unless your daughter developed it as part of another syndrome that is more directly inherited and predisposes future children for congenital heart defects, e.
g. Down's syndrome.

In brief: Depends
The genetic input to heart formation is complex and located on several chromosomes.
These change with every new pregnancy.The general rule is most heart defects are part of a complex random inheritance scheme. The chance of the same defect is relatively small, while the chance of any type of defect adds up to as high as 3-4 %.

In brief: Small but real
Future children are more likely to have a heart defect, but the risk remains small.
The risk increases from 0.8% in general, to 3-5% if you had a previous child with tetralogy of fallot. A prenatal cardiac ultrasound can be helpful.
