In brief: Yes
The genetics are often complex and vary depending upon the defect.
The risk of congenital heart disease overall is 8/1000. The risk of having a second child with congenital heart disease is higher after having the initial affected child. There are a few specific genetic conditions where the risk of having an affected child is 50%.

In brief: Depends
There are a few genetic syndromes that have chd where simple dominant or recessive patterns are described.
Most are sporadic & multifactorial. In most, parent to child risk is ~4-5% & not necessarily the same defect.If two parents have a chd risk is higher, risk of a second affected child after a 1st is ~8%.The best personal data is gained thru a family tree eval with a geneticist.
