Congenital heart disease is a large group of defects in the way the heart develops in the foetus when they are in the mother’s womb.
One child roughly in 100 is affected by congenital heart disease at birth.
The causes of congenital heart disease can be multiple. In some families, there can be a genetic defect that can cause the abnormal development of the heart.
In some other families, there can be diabetes during pregnancy or exposure to drugs or substances during pregnancy.
In other families, there is no clear cause for the abnormal development of the heart.
