The first successful implantation of an intravenous AAIR pacemaker into autologous extracardiac lateral tunnel Fontan in the child

Patients with a single ventricle have complex anatomy that requires staged palliation which is usually the Fontan procedure. This procedure has undergone a lot of modifications to improve hemodynamics. Despite these efforts, sinus node dysfunction (SND) and bradyarrythmias, are still common complications after Fontan operation, therefore there is a need of pacemakers implantation. Unfortunately, the most frequent technique of creating Fontan cannale – the extracardiac lateral tunnel makes the transvenous access to the atrium difficult or impossible to achieve.
