Congenital atrioventricular block, a fetal heart conduction defect, is linked to maternal autoimmune diseases. Advances in cardiac pacing offer effective treatment for affected children, though optimal pacing strategies require further study.

Area of Science:

  • Cardiology
  • Immunology
  • Pediatrics

Context:

  • Congenital atrioventricular block (CAVB) is a rare condition characterized by cardiac conduction defects present at birth.
  • It can be isolated or associated with structural heart disease, often linked to maternal autoimmune disorders like Sjögren's syndrome.
  • Maternal anti-Ro/SS-A and La/SS-B antibodies crossing the placenta can cause fetal inflammation and conduction system damage.

Purpose:

  • To define congenital atrioventricular block and its association with maternal autoimmune diseases.
  • To review diagnostic methods, including fetal echocardiography.
  • To discuss current understanding of prognosis and advancements in pediatric cardiac pacing.

Summary:

  • CAVB involves bradycardia in neonates without infection history, frequently associated with maternal autoantibodies.

  • Diagnosis can occur prenatally via echocardiography, which also monitors fetal well-being.
  • Long-term prognosis is less favorable than previously thought, necessitating careful follow-up and consideration of pacing.

    • Impact:

    • Highlights the role of maternal autoimmune antibodies in fetal cardiac conduction defects.
    • Emphasizes the need for specialized follow-up and tailored pacing strategies in pediatric CAVB patients.
    • Informs clinical practice regarding diagnosis, management, and long-term care for congenital heart block.
