In brief: ~3-5%

When a person has chd, or has a child with chd, their future offspring have a slightly higher risk of having chd as well (i'm sure you know this).
The quoted numbers differ, but most people agree that the risk is ~3-5% of having any form of chd.

In brief: Depends on the type

Heart defects are common and if one child has a congenital heart defect there is an increased risk in future siblings.
However, only 2-3% of congenital heart defects are related to a family history. The absolute chance of having a recurrence depends on the exact type of defect. Some conditions recur frequently while others recur rarely. Speak to a cardiologist for more details.

In brief: Depends on defect

The exact chances differ with different kinds of heart disease, and any comorbidities, such as hereditary disorders, but generally the chances are somewhat higher than the general population.

In brief: Other defects?

I agree with dr. Onyeije's note! additionally, i would be interested in knowing if that first infant had other birth defects or any identifiable syndrome by genetics - that would greatly affect recurrence risk calculations.
Multifactorial inheritance means that 2-5% of future babies will be affected. You can decrease that risk significantly (75%?) by taking Folic Acid before all future conceptions.
