The architecture of the cavotricuspid isthmus has been shown to be highly variable made of a large number of interspersed bundles in the majority. Targeting high-amplitude signals has resulted in short-ablation times, likely due to the selective ablation of such bundles. We report a series of cases where a single site ablation resulted in bidirectional block, supporting the hypothesis that conduction can occur over a discrete portion of the isthmus.
