Congenital heart defects happen in about 8 out of
1,000 babies born in the United States.1 About
one-third of these babies (2 to 3 out of 1,000 live births) have major defects
that need surgery or have defects that may cause death during the first year of
life.1 The number of congenital heart defects among
babies born early (premature) is much higher—about 2 out of 100 births.2
Congenital heart defects affect a similar number of boys and girls.
But the types of defects that are common in boys and girls tend to differ. Boys
tend to have a greater risk for certain defects such as complete transposition.
And girls tend to have a greater risk of other types of defects, such as atrial
or ventricular septal defects.3
