Excerpt
Ablation procedures for cavo-tricuspid isthmus (CTI)–dependent typical atrial flutter (AFL) have classically been guided by fluoroscopy, but nowadays, increasing evidence suggests that electro-anatomic mapping systems (EAM) may be useful to diminish fluoroscopy and guide ablation, targeting high voltage areas [
1‐
3]. Areas of slow conduction in the CTI are the primary substrate of the macroreentrant circuit [
4,
5]. We have tested a strategy of CTI ablation targeting areas of slow conduction and high voltage, identified with the omnipolar vectors (OV: maximum voltage vector determined from a triangular set of three electrodes, automatically selected from all directions), which allow obtaining improved voltage maps and detecting wave speed. …
