Prenatal care


Hello, doctor.
My first child was born with congenital heart disease (pulmonary valve atresia), and I am planning to conceive a second child.
What should I pay attention to (there is no family history of heart disease), or what tests should I undergo?

Dr. Wu Zongcheng reply Obstetrics and Gynecology


Congenital heart disease has (1) genetic factors: it is related to genetic defects, and currently, chromosome testing cannot diagnose it.
(2) Viral infections or medication effects during pregnancy.
What you can do now is to have regular check-ups after becoming pregnant, prevent viral infections (especially measles virus), and be cautious with medication use.

When planning for a second pregnancy, especially after having a child with congenital heart disease (CHD), it is essential to take several precautions and undergo specific evaluations to ensure the health of both the mother and the future child. Here are some essential prenatal care tips for families with a history of congenital heart disease:
1. Preconception Counseling: Before trying to conceive, it is crucial to consult with a healthcare provider, preferably a maternal-fetal medicine specialist or a cardiologist who specializes in congenital heart disease. They can assess your individual risk factors and provide tailored advice based on your medical history and the specifics of your first child's condition.

2. Genetic Counseling: Although your family history does not indicate a hereditary pattern of heart disease, genetic counseling can help assess the risk of CHD in future pregnancies. A genetic counselor can provide insights into the likelihood of recurrence and discuss any genetic testing options available.

3. Comprehensive Medical Evaluation: A thorough evaluation of your cardiovascular health is essential. This may include echocardiograms or other imaging studies to assess your heart's function and structure. Understanding your heart health can help manage any potential risks during pregnancy.

4. Prenatal Vitamins and Nutrition: Start taking prenatal vitamins that contain folic acid before conception and throughout pregnancy. Folic acid is crucial in reducing the risk of neural tube defects and may have a role in reducing the risk of congenital heart defects. A balanced diet rich in fruits, vegetables, whole grains, and lean proteins is also vital for overall health.

5. Monitoring During Pregnancy: Once pregnant, regular prenatal visits are essential. Your healthcare provider will likely recommend more frequent monitoring due to your previous child's heart condition. This may include ultrasounds to monitor fetal development and echocardiograms to assess the baby's heart.

6. Avoiding Teratogens: Be mindful of substances that could harm fetal development. This includes avoiding alcohol, tobacco, and certain medications that may pose risks during pregnancy. Always consult your healthcare provider before taking any new medications.

7. Managing Pre-existing Conditions: If you have any pre-existing health conditions (e.g., diabetes, hypertension), it is crucial to manage these effectively before and during pregnancy. Poorly controlled conditions can increase the risk of complications for both mother and baby.

8. Planning for Delivery: Discuss your delivery plan with your healthcare provider. Depending on your heart condition and overall health, they may recommend delivering in a facility equipped to handle potential complications related to congenital heart disease.

9. Postpartum Care: After delivery, be aware of your health and the baby's health. Some congenital heart defects may not be immediately apparent, so ensure that your newborn receives a thorough evaluation, including pulse oximetry screening to check for critical congenital heart defects.

10. Support Systems: Consider joining support groups for families with children who have congenital heart disease. These groups can provide valuable resources, emotional support, and shared experiences that can help you navigate your journey.

In summary, while having a child with congenital heart disease can be concerning when planning for another pregnancy, proactive measures, thorough evaluations, and regular monitoring can significantly improve outcomes. Always maintain open communication with your healthcare team to ensure the best possible care for you and your future child.
