“…In our group, we managed to effectively isolate 98.1% of all pulmonary veins in 118 out of 126 patients (93.7%), with a low complication rate and acceptable arrhythmia-free survival (60,3%) at the 12-month follow up. These results are comparable with previously published data, regarding the phased-radiofrequency technique [6,7,8,9,10,21], including the recently published initial results from the multicenter GOLD AF registry [22], in which complete acute PV isolation was achieved in 93.8% of patients. Interestingly, the relapse in the blanking period was the strongest independent predictor ( p < 0.0001) of AF recurrence in long-term follow-up, which stands in line with earlier observations regarding both RF [23,24,25] and cryoablation [26] and supports the opinion that blanking-period relapses are possible signs of early PV reconnection.…”

Background: Pulmonary vein isolation (PVI) is a routine treatment in atrial fibrillation (AF). Single-shot techniques were introduced to simplify the procedure. We analyzed time-dependent changes in procedural parameters, acute success, complication rates, and long-term outcomes during our initial experience with multipolar phased-radiofrequency (RF) ablation. Methods and Results: The first 126 consecutive patients (98 male; age: 58.8 ± 8.7 years) who underwent PVI with phased-RF ablation at our center were included in the study. Procedural parameters, complication rate, acute success and 12-month efficacy were compared in the first, second and third group of 42 consecutive patients. In all patients, 516/526 PVs were effectively isolated (98.1%), with no differences between the tierces (p = 0.67). Procedure (169.8 vs. 132.9 vs. 105.8 min, p < 0.0001), fluoroscopy (32.9 vs. 24.3 vs. 14.1 min, p < 0.0001) and left atrial dwell (83.0 vs. 61.9 vs. 51.4 min, p < 0.0001) times were significantly reduced with experience in tierces 1–3, respectively. In the 12-month follow-up, 60.3% of patients were arrhythmia-free with no differences between the tierces (p = 0.88). In multivariate analysis, the relapse in the blanking period (p < 0.0001), time from AF diagnosis (p = 0.004) and left atrial diameter (p = 0.012) were the only independent predictors of AF recurrence. Conclusions: The learning curve effect was demonstrated in procedural parameters, but not in the complication rate nor the long-term success of PVI with phased-RF technique. The relapse in the blanking period was the strongest predictor of treatment failure in long-time observation.

“…While the FDA approval of the phased RF technology is no longer being pursued, the system is commercialized outside of the US making the results of this study clinically relevant. Other publications using PVAC GOLD have demonstrated comparable efficacy and safety when compared to first‐generation PVAC 14‐17 …”

Introduction: The VICTORY AF Study was designed to evaluate the risk of the procedure and/or device-related strokes in patients with PersAF on warfarin undergoing ablation with a phased radiofrequency (RF) system. Methods:The VICTORY AF trial was a prospective, multicenter, single-arm, investigational study. PersAF patients on vitamin K antagonism without major structural heart disease or history of stroke/transient ischemic attack undergoing phased RF ablation for atrial fibrillation (AF) were included. The primary outcome was the incidence of the procedure and/or device-related stroke within 30 days of the ablation by a board-certified neurologist's assessment. The secondary outcomes were an acute procedural success, 6 months effectiveness (defined as the reduction in AF/atrial
