Planning for pregnancy if you have a congenital heart defect
Although the specific cause of a
congenital heart defect usually is not known, genetics
probably play a large role. For this reason,
genetic counseling is recommended if you or your
partner has a congenital heart defect and you are considering becoming
pregnant. It may be that a baby (fetus) is at higher risk for congenital heart
defects when the mother, rather than the father, has this condition.1
Issues to consider regarding pregnancy
If you have a congenital heart defect, your pregnancy may be
considered high-risk. Specific issues will need to be addressed with your
health professional, such as:
- Whether it is safe to become
pregnant.
- The timing and method of delivery.
- The type
of anesthesia or medicines that are safe to use during labor.
- How
you will be monitored throughout your pregnancy.
- Whether you need
to take antibiotics to prevent
endocarditis.
You may have a cardiologist involved with your care throughout your
pregnancy and delivery. A fetal echocardiogram can be done as early as 16 to 18
weeks of pregnancy to check for congenital heart defects in the fetus. Other
testing such as
chorionic villus sampling or
amniocentesis may be done.
Birth control options if you have a congenital heart defect
If you have a congenital heart defect, you also will need to
carefully consider the type of birth control you use. In general:
- Barrier devices (condoms, diaphragms) and
low-dose birth control pills are safest.
- Intrauterine devices
(IUDs) generally are not recommended because of the potential risk of infection
and bleeding.
Additionally, hormone (progestin) injections are not recommended
for most women who develop
heart failure from heart defects. These injections may
increase fluid retention.
