Abstract

Abstract: Rhabdomyomas are not uncommon in infants with tuberous sclerosis. We describe a neonate who presented with hydrops fetalis arising from a tachyarrhythmia during fetal life related to rhabdomyomas. After reversion of the arrhythmia, pre-excitation was noted on an interval electrocardiogram. Following regression of the tumours, the delta wave disappeared with no further arrhythmias noted.
