Complete Congenital Heart Block in a Newborn Associated with Maternal Systemic Lupus Erythematosus: A Case Report
Keywords:Congenital Heart Block, Systemic Lupus Erythematosus, Bradycardia, SS-A Antibodies
Background: Complete Congenital Heart Block (CCHB) is a rare disease of the newborn that carries significant morbidity and mortality. CCHB can be diagnosed early or late in life. In newborns, it is usually associated with maternal autoantibodies or a congenital cardiac structural abnormality. The most common presentation of CCHB is bradycardia that can be diagnosed by an electrocardiogram.
Results: This is a case report of a male infant born to a mother with an autoimmune disease, Systemic Lupus Erythematosus (SLE), who was found to have third degree heart block at birth.
Conclusion: Early diagnosis and prompt management of the case is important for a better prognosis and prevention of associated complications. Neonates with CCHB should be managed at a tertiary care center and the only definite treatment is insertion of a pacemaker. Moreover, prenatal diagnosis and specific obstetric counseling of pregnant women with SLE along with careful monitoring with serial ultrasonography and echocardiography are of paramount importance in prevention of the disease in subsequent offspring.
