Figure 3: Procedural Data. A) Fractionation maps: The ganglionated plexi (GP) were found in the same locations as in her first cardioneuroablation (CNA), at the posterior right atrial (RA) GP, posteromedial RA GP, left anterior GP, left inferior GP, and right anterior GP, correlating with expected anatomy. B)Radiofrequency (RF) ablation: At the posterior RA GP, she exhibited a tachycardic response to RF characteristic of vagal denervation. C) Final lesion set: Due to a lack of high-frequency stimulation (HFS) responses, repeat CNA was performed based on anatomy and fractionation mapping.
