Isolated congenital complete heart block: longterm outcome of children and immunogenetic study.

Abstract

Patients with isolated CCHB have significant cardiac mortality, and after a long followup many of them are paced to control symptoms, but in our small sample those who survive the perinatal period mostly lead a normal life. The longterm immunological outcome of these children seems good. CCHB is not related to a specific HLA pattern in affected children.
