Key result
Associated structural heart disease in congenital complete heart block linked to highest neonatal mortality.
Why the study?
The study aimed to describe the clinical characteristics, treatment, and outcomes of fetal and neonatal congenital complete heart block diagnosed in utero or at birth.

Alerts clinicians to mortality risk with structural disease; case series leaves optimal pacing thresholds open for prospective study.
Observational (n=15)
Congenital complete heart block is frequently associated with structural heart disease (which carries higher mortality) or maternal connective-tissue disease antibodies.
Davison et al. (1989) conducted an observational in Congenital complete heart block (n=15). Congenital complete heart block was evaluated on Mortality and requirement for ventricular pacing. Among 15 cases of congenital complete heart block, 7 required ventricular pacing and mortality was highest in patients with associated structural heart disease (3 neonatal deaths).
