Hypoplastic left heart syndrome (HLHS), is a heart condition that is present at birth, and often is called a congenital heart
defect. HLHS is a group of related heart defects that, together, mean that the left side of the heart is underdeveloped.
There is no known cause for HLHS. The problem develops before birth when there is not enough growth of the left side of the
heart. White babies seem to have higher rates of HLHS than babies of other races or ethnicities. Maternal multivitamin use
before and during pregnancy appears to decrease the risk of HLHS.
