Hole in the heart and open surgery? Will my baby have a chance of having it?

Slight increased rsk. Heart defects generally occur at random & are influenced by multiple genes. They are not directly passed down. There is an increased general risk of some heart defect (not necessarily the same one) quoted as ~5% from parent to child. If both parents have some defect the risk would be higher.Genetic counseling with review of a family tree could provide u with specific risks.
