Abstract:
The Fontan circulation is a palliative surgery used to treat cardiac abnormalities with only one well-developed ventricle. Although the surgical epicardial pacing is usually preferred, in a few cases the transvenous placement of a permanent atrial lead can be considered. The transvenous endocardial pacing is challenging because most of the right atrium is fibrotic and the lead positioning needs to be supported by a long sheath. We report a case of a transvenous lead placement from a typical left pre-pectoral pocket guided by electro-anatomical mapping.

Anatomy of the Heart
The Cardiac Cycle
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and empty blood into the...

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
