Transvenous pacing approach for atrioventricular block in fontan - Possibility of transvenous approach by electrophysiological assessment.

In extracardiac Fontan, an epicardial pacemaker implantation has many limitations, especially given that it is highly invasive and a high-risk procedure due to repeat thoracotomy. Herein we illustrate a case with the possibility of transvenous pacing in extracardiac Fontan being less invasive and lower risk transvenous dual-chamber pacemaker implantation by electrophysiological assessment. < Learning objective: Transvenous pacemaker implantation via left superior vena cava may be a viable alternative to epicardial pacing with a minimally invasive procedure in patients with extracardiac Fontan.>.
