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.
