Abstract

Congenital complete atrioventricular heart block(CCAVB) is a rare disease of the newborn that carries significant mortality and has a heterogenous etiology. It may occur as a result of the presence of maternal autoantibodies that are transferred to the fetus and affect the fetal heart or be associated with a congenital structural abnormality of the heart. Infants with CCAVB are at risk of diminished cardiac output and the subsequent development of congestive heart failure. We report two cases of CCAVB in newborns treated with pacemaker implantation after birth. The first case revealed CCAVB with patent ductus arteriosus and anti- Ro(SS-A) antibody in both of the mother and the newborn. The second case was accompanied with mitral regurgitation and tricuspid regurgitation, but anti-Ro(SS-A) antibody was absent in both of the mother and the newborn. Pacemaker implantation was performed for both cases and the result was favorable. We concluded that our experience supports that the pacemaker implantation in the newborn is feasible and beneficial in the treatment of CCAVB.
