ABSTRACT
We discuss a case of symptomatic atrial arrhythmia in a 31 year old man who had previously undergone extra-cardiac Fontan surgery and a MAZE procedure. Besides the peculiar anatomy that restricted percutaneous atrial access only by perforation through the extra-cardiac tunnel, changing cycle lengths of the tachycardua necessitated innovative mapping to define the electro-morphology of the arrhythmia.
