Hello,
With the question “Can women with congenital heart disease pass it on to their children? ", the doctor would like to answer as follows:
Some diseases such as hypertrophic cardiomyopathy (genes can be found), Brugada syndrome, arrhythmia can have a high familial nature. Until now, scientists have not pinpointed the exact cause of the disease, but most congenital heart disease is related to more or less familial nature. If a parent or sibling has congenital heart disease, the chances of the child being born with congenital heart disease are quite high, more than 3 times higher than normal. If the gene is dominant, up to 50% of the offspring will have it. However, not every congenital heart disease will give birth to a child with congenital heart disease, and if you are healthy, you will have a normal baby because there are genetic mutations that can occur.
