Congenital Heart Defects - What Happens
Congenital heart defects happen when the heart doesn't form normally as the developing baby (fetus) grows in the uterus. Heart defects may
cause problems with
blood flow through the heart after a baby is born. The problems can affect the
baby's blood and oxygen supply.
There are many types of congenital heart defects. If the defect lowers the amount of oxygen in the body, it is called cyanotic. If the defect doesn't affect oxygen in the body, it is called acyanotic. Some defects require treatment right away. Other defects get better on their own
and don't require treatment.
one-third of full-term babies born with a congenital heart defect have major defects
that need surgery or have defects that may cause death during the first year of
Not all defects are found when a child is very young. Some defects don't cause symptoms and aren't life-threatening. These defects may not
be found until the teen years or later.
Some children have a shorter life span than average if
their defect is severe or if heart failure or
other complications happen.
Many children and adults
with corrected heart defects lead healthy lives. But the treatments they've had or the defect itself can cause or be related to long-term problems. These include:
- Developmental delays or disabilities or
- Certain physical
traits, such as smaller-than-average adult height and weight,
clubbing, or cyanosis (bluish tint to the skin from
low blood-oxygen levels). These can present challenges to a person's
self-esteem and confidence.
