Types of heart abnormalities


There are many types of heart abnormalities. Only the more common ones are described    below. Some children have more than one problem with their heart and perhaps more than one diagram will then be relevant to that child.

Do not worry if your child’s condition is not specifically described here. Seek the advice of your cardiologist, and if appliacble, surgeon, for detailed explanations, management and treatment of the various conditions. The following section is replicated from the excellent and practical handbook for parents titled ‘Heart Children’.
