Use of the Abbott EnSite Precision three-dimensional mapping system for the placement of an atrial pacemaker lead in a patient with congenital heart disease.

Abstract

We report the use of the Abbott three-dimensional mapping system (EnSite Precision) for the placement of an atrial pacemaker lead in a patient after modified Fontan procedure. The mapping system was used for the identification of a promising pacing site in the complexly modified right atrium and to visualize the successful placement of an atrial lead at the same spot.
