Background  Disappearance of pulmonary vein ( PV ) potentials is an important indicator of successful  PV  isolation during cryoballoon ablation. Conventional octapolar 20‐mm‐diameter circular  PV  mapping catheters occasionally fail to identify persistent  PV  potentials. A new decapolar 25‐mm‐diameter circular  PV  mapping catheter has been introduced to improve the detection of  PV  potentials and their elimination. We compared the detection rates of  PV  potential disappearance between the decapolar and the octapolar  PV  mapping catheters.    Methods and Results  A total of 44 consecutive patients (175  PV s) undergoing initial cryoballoon ablation for atrial fibrillation were included. The decapolar catheter was used for 79 (45%)  PV s in 20 (45%) patients. There was no difference in left atrial diameter or  PV  diameter in patients mapped with the two catheters. The decapolar mapping catheter demonstrated a significantly higher detection rate of  PV  potential disappearance than the octapolar catheter. The need for touch‐up ablation was similar between the two groups (5% vs 8%,  P  =   0.39). When  PV  potentials were identified, the decapolar catheter detected significantly higher‐amplitude  PV  potentials than the octapolar catheter. In multivariate analysis, use of the decapolar catheter was an independent predictor of the detection of  PV  potential disappearance.    Conclusions  The decapolar  PV  mapping catheter demonstrated improved detection of  PV  potential disappearance in cryoballoon  PV  isolation.
