Atriofascicular pathways are a rare cause of antidromic atrioventricular reciprocating tachycardia. The IntellaTip MiFi ablation catheter (Boston Scientific, MA, USA) is a novel ablation catheter that allows enhanced signal clarity with highly localized electrograms. This is the first report of this catheter being successfully used to map and ablate the atriofascicular pathway potentials.
