BACKGROUND: Ablation of the @entity713 ( @entity713 ) combined with pacemaker implantation (the "ablate and pace" approach) has been an effective treatment strategy for @entity1 with @entity955 ( @entity955 ) when rate control is the goal of therapy and when rapid ventricular rates during @entity955 is refractory to pharmacologic therapy. OBJECTIVE: This report describes the feasibility and safety of catheter ablation of @entity713 via a superior vena cava ( @entity6480 ) approach performed during concurrent pacemaker or defibrillator implantation. METHODS: A total of 170 consecutive @entity1 with drug-refractory @entity955 underwent combined @entity713 ablation and pacemaker or defibrillator implantation using the axillary or subclavian @entity1211 . The acute and long-term success of achieving complete atrioventricular (AV) block, the impact of the ablation procedure on the total procedure time and fluoroscopy duration, and procedural complications were evaluated. RESULTS: A dual-chamber device in 61% of @entity1 and biventricular device in 39% @entity1 . Catheter ablation of the @entity713 was acutely successful in 166 @entity1 (97.6%). The mean procedure time of the @entity713 ablation was 7.0    3.3 minutes and the mean fluoroscopy time during the ablation procedure was 3.1    3.2 minutes. The average duration of @entity6470 energy application required to achieve complete @entity713 was 129    65 seconds. Procedural complications were observed in seven @entity1 . Complete @entity713 persisted in 96% of @entity1 during a mean follow-up of 26    16 months. CONCLUSION: Catheter ablation of the @entity713 can be performed successfully and safely using the @entity6480 approach in @entity1 undergoing concurrent device implantation, and it may offer several advantages over the conventional femoral approach.
