Nevertheless, today we have a small amount of information related to risk factors, especially infectious, environmental and behavioral factors that can have an adverse effect on the development of the fetal heart; in our opinion, this lack of information represents a serious obstacle in the prevention of congenital heart defects. After reviewing a lot of literature and articles, we came to the conclusion that information regarding risk factors for congenital heart defects is extremely scarce. In this population-based study, we sought to investigate and show the relationship between chronic maternal diseases and congenital heart defects in their children.
