Navigating Congenital Heart Block: A Guide for Parents

At a Glance

Congenital heart block (CHB) is a serious fetal heart rhythm condition often linked to maternal autoantibodies. With specialized prenatal monitoring, careful birth planning, and potentially a newborn pacemaker, care teams can manage the baby's health and evaluate the mother's autoimmune risks.

Receiving a diagnosis of congenital heart block (CHB) for your baby can feel like the world has suddenly shifted beneath your feet. It is natural to feel a rush of fear, confusion, and an overwhelming need to protect your child. While this diagnosis is serious, it is important to take a breath and recognize that you are now in the hands of a specialized medical team with a clear roadmap for care.

This guide is designed to empower you with the knowledge you need to navigate this journey—from understanding the biology of the condition to planning for delivery and looking ahead to your child’s long-term future.

Mother’s Health matters too

If your baby’s diagnosis is linked to maternal autoantibodies (anti-Ro/SSA or anti-La/SSB), it is crucial to remember that your health matters too. Carrying these antibodies means you may be at a higher risk for underlying autoimmune conditions, such as Sjögren’s syndrome or lupus, even if you currently have no symptoms [1]. Establishing care with a rheumatologist is an important step to ensure you are monitored and healthy for years to come.

Common questions in this guide

Why do I need to see a rheumatologist if my baby has congenital heart block?
If your baby's condition is linked to maternal autoantibodies, you may be at a higher risk for autoimmune conditions like Sjögren's syndrome or lupus. A rheumatologist can monitor your health to ensure you remain healthy, even if you currently have no symptoms.
Which doctors will be part of my baby's care team?
Your baby's care will be coordinated by a specialized team of doctors. This typically includes your obstetrician, a pediatric cardiologist who specializes in children's hearts, and a neonatologist who cares for newborns needing extra medical attention.
Will my baby need a pacemaker for congenital heart block?
Many newborns with congenital heart block will require a pacemaker. This specialized device is placed after birth to help the baby's heart maintain a safe and regular rhythm.
What does prenatal care look like after a congenital heart block diagnosis?
You will undergo frequent prenatal monitoring throughout the rest of your pregnancy. This includes specialized ultrasounds to monitor your baby's heart rate and development, and you may be prescribed preventative medications.
