Example of index procedure with remap. Patient from the subset population in which reconnection of the RSPV was observed at the time of the mandatory repeat study. (A) Activation map during pacing at the ostium of the coronary sinus during remapping procedure. The reconnection of the RSPV was based on a small gap at the posterior carina of the right circle. (B) Ablation set from the index procedure. The contiguity of the circle suggests that non-transmurality of the PF application is the cause of reconnection at the carina. LAT, local activation time; PF, pulsed field; PFA, pulsed field ablation; RF, radiofrequency; RSPV, right superior pulmonary vein. Images are courtesy of © Biosense Webster, Inc. All rights reserved.
