Background: Pulsed field ablation (PFA) is a non-thermal energy source with promising safety and efficacy advantages. We aimed to develop a convenient, safe, effective and fast method of pulmonary vein isolation (PVI) utilizing a penta-spline PFA catheter via a single femoral vein and a venous closure system.Methods and Results: Consecutive patients (n=50; mean age: 63.6±10.7 years, 38% female) presenting with AF (paroxysmal AF: 56%) underwent first-time PVI via PFA. A single ultrasound-guided femoral vein puncture and a single transseptal puncture were used. After PVI using the penta-spline PFA catheter, extra pulse trains were added to the posterior wall for wide antral circumferential ablation. A venous closure system was used and a Donati suture was performed. The pressure bandage was removed after 1 h. A total of 196 PVs were identified and isolated with PFA only. The mean procedural time was 27.4±6.6 min, and the mean dwelling time was 14.4±5.5 min. Time to ambulation was 3.3±3.1 h. No severe complications occurred. During a mean follow-up of 6.5±2.1 months, 41/50 patients (82%) remained in sinus rhythm.Conclusions: The combination of a single venous puncture, single transseptal puncture approach using PFA and vascular closure device resulted in a 100% rate of acute PVI and an extraordinarily fast procedure and time to ambulation. The rate of periprocedural complications was low.

Background:The arctic front cryoballoon (AF-CB) provides effective and durable pulmonary vein isolation (PVI) associated with encouraging clinical outcome. The POLARx cryoballoon incorporates unique features and design changes that may translate into improved efficacy, safety and further simplified balloon-based procedures. Efficacy and safety of the novel POLARx cryoballoon was compared to the fourth generation AF-CB (AF-CB4).Methods and Results:Twenty-five consecutive patients with paroxysmal or persistent atrial fibrillation were prospectively enrolled, underwent POLARx-based PVI (POLARx group) and were compared to 25 consecutive patients treated with the AF-CB4 (AF-CB4 group). All PVs were successfully isolated utilizing the POLARx and AF-CB4. A significant difference regarding the mean minimal cryoballoon temperatures reached using the AF-CB4 and POLARx (−50±6℃ vs. −57±7℃, P=0.004) was observed. Real-time PVI was visualized in 81% of POLARx patients and 42% of AF-CB4 patients (P<0.001). Utilizing the POLARx, a trend towards shorter median procedure time (POLARx: 45 [39, 53] min vs. AF-CB4: 55 [50, 60] min; P=0.062) was found. No differences were observed between AF-CB4 and POLARx concerning catheter maneuverability, catheter stability and periprocedural complications.Conclusions:The novel POLARx showed similar safety and efficacy compared to the AF-CB4. A higher rate of real-time PV recordings and significantly lower minimal balloon temperatures were observed using the POLARx.
