Anti‐Ro52/SSA antibody‐exposed fetuses with prolonged atrioventricular time intervals show signs of decreased cardiac performance

Abstract

The ICT is an important contributor to prolongation of AV time intervals. This observation suggests that anti-Ro52/SSA antibody-exposed fetal hearts have not only disturbed electrical conduction but also decreased mechanical performance. Moreover, our findings have implications for the interpretation of AV time intervals used for surveillance of fetuses at risk for developing CHB.
