Isolated congenital complete heart block: longterm outcome of mothers, maternal antibody specificity and immunogenetic background.

Abstract

The longterm outcome for the mothers of children with CCHB is more reassuring than generally assumed. All the mothers were anti-Ro positive by sensitive ELISA: Reactivity to the denaturated 52 kDa SSA(Ro) component seems characteristic of these mothers, who presented a particular immunogenetic background.
