AB  - BACKGROUND: Intracardiac electrogram recording is influenced by the electrode
      size and inter-electrode spacing. Smaller electrodes with a closer
      inter-electrode spacing may improve the mapping resolution and outcome. METHODS: 
      Substrate mapping of the left atrium and residual pulmonary vein (PV) potentials 
      during sinus rhythm was sequentially performed using a 3.5-mm electrode tip
      catheter and a 1-mm electrode multielectrode catheter in 33 patients (Group 1)
      that underwent repeat atrial fibrillation (AF) procedures. PV gap identification 
      and electrophysiological characteristics were compared. Arrhythmia freedom was
      compared with a propensity matched (1:2) control group (66 patients, Group 2)
      undergoing repeat AF procedures guided by wide inter-electrode spacing catheter. 
      RESULTS: In the Group 1 patients, the total area of residual PV potentials
      measured using the 1-mm catheter was larger than that measured by the 3.5-mm
      catheter. Overall 1.97+/-0.59 (1-3) and 1.49+/-0.62 (1-3) PVs were identified by 
      the 1-mm electrode and 3.5mm catheters, respectively (P=0.02). The gaps not
      identified by the 3.5mm catheter had a smaller width and lower voltage.
      Radiofrequency catheter ablation in the areas with residual PV potentials
      identified by the 1-mm catheter resulted in complete electrical isolation of the 
      PVs. Arrhythmia freedom at one year of follow-up was achieved in 26 of 33 (78.8%)
      patients in Group 1, which was significantly higher than the matched control
      group (33/66 [50%], P<0.05). CONCLUSION: In the patients with a previous PV
      isolation, mapping with small, closely spaced electrodes can increase the
      detection rate of residual PV potentials and improve the outcome.
