To compare high-power (HP) vs. conventional-power (CP) radiofrequency ablation for atrial fibrillation (AF).
We retrospectively enrolled AF patients undergoing CP (30-40 W, 43 patients) or HP (50 W, 49 patients) radiofrequency ablation. Immediate pulmonary vein (PV) single-circle isolation, PV-ablation time, AF recurrence, AF recurrence-free survival, and complications were analyzed.
Diabetes was more common in the CP group than in the HP group (27.91% vs. 10.20%, = 0.029). The left PV single-circle isolation rate (62.79% vs. 65.31%), right PV single-circle isolation rate (48.84% vs. 53.06%), and bilateral PV single-circle isolation rate (32.56% vs. 38.78%; all > 0.05) did not differ between the groups. Single-circle ablation times for the left PVs (12.79 ± 3.39 vs. 22.94 ± 6.39 min), right PVs (12.18 ± 3.46 vs. 20.67 ± 5.44 min), and all PVs (25.85 ± 6.04 vs. 45.66 ± 11.11 min; all < 0.001) were shorter in the HP group. Atrial fibrillation recurrence within 3 months (13.95% vs. 18.37%), at 3 months (11.63% vs. 8.16%), and at 6 months after ablation (18.60% vs. 12.24%; all > 0.05) was similar in both groups. Atrial fibrillation recurrence-free survival did not differ between the groups (Kaplan-Meier analysis). Cardiac rupture and pericardial tamponade did not occur in any patient. Pops occurred in 2 and 0 patients in the HP and CP groups, respectively (4.08% vs. 0.00%, = 0.533).
High-power ablation improved operation time and efficiency without increasing complications.
比较高功率(HP)与传统功率(CP)射频消融治疗心房颤动(AF)的效果。
我们回顾性纳入了接受CP(30 - 40瓦,43例患者)或HP(50瓦,49例患者)射频消融的AF患者。分析即刻肺静脉(PV)单环隔离、PV消融时间、AF复发、无AF复发生存率及并发症情况。
CP组糖尿病患者比HP组更常见(27.91%对10.20%,P = 0.029)。两组间左PV单环隔离率(62.79%对65.31%)、右PV单环隔离率(48.84%对53.06%)及双侧PV单环隔离率(32.56%对38.78%;均P > 0.05)无差异。HP组左PVs单环消融时间(12.79 ± 3.39对22.94 ± 6.39分钟)、右PVs单环消融时间(12.18 ± 3.46对20.67 ± 5.44分钟)及所有PVs单环消融时间(25.85 ± 6.04对45.66 ± 11.11分钟;均P < 0.001)更短。两组在消融后3个月内(13.95%对18.37%)、3个月时(11.63%对8.16%)及6个月时(18.60%对12.24%;均P > 0.05)的AF复发情况相似。两组间无AF复发生存率无差异(Kaplan - Meier分析)。所有患者均未发生心脏破裂和心包填塞。HP组和CP组分别有2例和0例患者发生爆裂声(4.08%对0.00%,P = 0.533)。
高功率消融可改善手术时间和效率,且不增加并发症。
