title: Optimal pacing in congenital complete atrioventricular block of immunological origin: interest of multisite stimulation.
abstract: An infant with a congenital auriculoventricular block (CAVB) of immunological origin was diagnosed prenatally. The mother had Gougerot-Sjögren disease with positive anti-Sjogren's Syndrome A (SSA) and Sjogren's Syndrome B (SSB) serologies. Cardiac pacing was necessary and the epicardial route was chosen. Considering the left ventricular (LV) dilatation, bi-ventricular (BiV) stimulation was preferred to the usual DDD mode, presumed to have a deleterious long-term effect. Echographic parameters were better with BiV stimulation: the asynchronism induced by mono-RV stimulation was corrected and the QRS complexes were narrower. BiV pacing of a CAVB with LV dilation looks clinically and echographically attractive but needs to be validated in the long term.
