title: Atrioventricular block following implantation of a stent in the oval fossa.
abstract: A neonate weighing 2.8 kilograms underwent the staged hybrid procedure for palliation of hypoplastic left heart syndrome. Within 6 hours following placement of a stent to retain patency of the interatrial communication, the infant developed second degree atrioventricular block, which resolved within 24 hours. Four days later, the patient developed complete atrioventricular dissociation. Removal of the stent was followed by recovery of atrioventricular conduction.
