Objective The risk of procedure-related complications and rhythm outcomes differ between men and women after atrial fibrillation catheter ablation (AFCA). We evaluated whether consistent sex differences existed in mapping and rhythm outcomes in repeat ablation procedures. Methods Among 3282 patients in the registry, we analysed 443 consecutive patients (24.6% female, 58.5±10.3 years old, 61.5% with paroxysmal atrial fibrillation) who underwent a second AFCA. We compared the clinical factors, mapping, left atrial (LA) pressure, complications and long-term clinical recurrences after propensity score matching. Results LA volume index (43.1±18.6 vs 35.8±11.6 mL/m2, p<0.001) was higher, but LA dimension (40.0±6.8 vs 41.6±6.3 mm, p=0.018), LA voltage (0.94±0.55 vs 1.20±0.68 mV, p=0.002) and pericardial fat volume (89.5±43.1 vs 122.1±53.9 cm3, p<0.001) were lower in women with repeat ablation than in their male counterparts. Pulmonary vein (PV) reconnections were lower (58.7% vs 74.9%, p=0.001), but the proportion of extra-PV triggers (27.5% vs 17.0%, p=0.026) and elevated LA pulse pressures (79.7% vs 63.7%, p=0.019) was significantly higher in women than in men. There was no significant sex difference in the rate of procedure-related complications (4.6% vs 4.2%, p=0.791). During a 31-month (8–60) median follow-up, clinical recurrences were significantly higher in women after both the de novo procedure (log-rank p=0.039, antiarrhythmic drug (AAD)-free log-rank p<0.001) and the second procedure (log-rank p=0.006, AAD-free log-rank p=0.093). Female sex (HR 1.51, 95% CI 1.06 to 2.15, p=0.023), non-paroxysmal atrial fibrillation (HR 1.78, 95% CI 1.30 to 2.34, p<0.010) and extra-PV triggers (HR 1.88, 95% CI 1.28 to 2.75, p=0.001) were independently associated with clinical recurrences after repeat procedures. Conclusions During repeat AFCA procedures, PV reconnections were lower in women than in men, and the existence of extra-PV triggers and an LA pressure elevation were more significant, which resulted in poor rhythm outcomes.

重复房颤消融的映射和节律结果的性别差异

目的 心房颤动导管消融 (AFCA) 后,男性和女性的手术相关并发症风险和节律结果不同。我们评估了重复消融程序中的映射和节律结果是否存在一致的性别差异。方法 在登记的 3282 名患者中,我们分析了 443 名接受第二次 AFCA 的连续患者(24.6% 女性,58.5±10.3 岁,61.5% 患有阵发性房颤)。我们比较了倾向评分匹配后的临床因素、映射、左心房 (LA) 压力、并发症和长期临床复发。结果 LA 体积指数(43.1±18.6 vs 35.8±11.6 mL/m2,p<0.001)较高,但 LA 尺寸(40.0±6.8 vs 41.6±6.3 mm,p=0.018),LA 电压(0.94±0.55 vs 1.20±) 0.68 mV,p=0.002)和心包脂肪体积(89.5±43.1 vs 122.1±53.9 cm3,p<0。001) 在重复消融的女性中低于男性。肺静脉 (PV) 重新连接较低(58.7% 对 74.9%,p=0.001),但额外 PV 触发的比例(27.5% 对 17.0%,p=0.026)和 LA 脉压升高(79.7% 对 63.7%) , p=0.019) 在女性中显着高于男性。手术相关并发症的发生率没有显着的性别差异(4.6% vs 4.2%,p=0.791)。在 31 个月 (8-60) 的中位随访期间,在两次从头手术后,女性的临床复发率显着更高(对数秩 p=0.039,无抗心律失常药物 (AAD) 对数秩 p<0.001)和第二个程序(log-rank p=0.006,AAD-free log-rank p=0.093)。女性(HR 1.51,95% CI 1.06 至 2.15,p=0.023),非阵发性房颤(HR 1.78,95% CI 1.30 至 2.34,p<0。010)和额外 PV 触发因素(HR 1.88,95% CI 1.28 至 2.75,p=0.001)与重复手术后的临床复发独立相关。结论在重复AFCA手术中,女性PV重连率低于男性,额外PV触发和LA压力升高的存在更为显着,导致心律结果不佳。试验注册号 [NCT02138695][1]。与研究相关的所有数据都包含在文章中或作为补充信息上传。数据、分析方法和研究材料可应合理要求提供给想要重现结果或重复程序的其他研究人员。[1]:/lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT02138695&atom=%2Fheartjnl%2F107%2F23%2F1862.atom 001) 与重复手术后的临床复发独立相关。结论在重复AFCA手术中,女性PV重连率低于男性,额外PV触发和LA压力升高的存在更为显着,导致心律结果不佳。试验注册号 [NCT02138695][1]。与研究相关的所有数据都包含在文章中或作为补充信息上传。数据、分析方法和研究材料可应合理要求提供给想要重现结果或重复程序的其他研究人员。[1]:/lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT02138695&atom=%2Fheartjnl%2F107%2F23%2F1862.atom 001) 与重复手术后的临床复发独立相关。结论在重复AFCA手术中,女性PV重连率低于男性,额外PV触发和LA压力升高的存在更为显着,导致心律结果不佳。试验注册号 [NCT02138695][1]。与研究相关的所有数据都包含在文章中或作为补充信息上传。数据、分析方法和研究材料可应合理要求提供给想要重现结果或重复程序的其他研究人员。[1]:/lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT02138695&atom=%2Fheartjnl%2F107%2F23%2F1862.atom 女性的 PV 重新连接低于男性,并且额外 PV 触发的存在和 LA 压力升高更为显着,这导致了较差的节律结果。试验注册号 [NCT02138695][1]。与研究相关的所有数据都包含在文章中或作为补充信息上传。数据、分析方法和研究材料可应合理要求提供给想要重现结果或重复程序的其他研究人员。[1]:/lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT02138695&atom=%2Fheartjnl%2F107%2F23%2F1862.atom 女性的 PV 重新连接低于男性,并且额外 PV 触发的存在和 LA 压力升高更为显着,这导致了较差的节律结果。试验注册号 [NCT02138695][1]。与研究相关的所有数据都包含在文章中或作为补充信息上传。数据、分析方法和研究材料可应合理要求提供给想要重现结果或重复程序的其他研究人员。[1]:/lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT02138695&atom=%2Fheartjnl%2F107%2F23%2F1862.atom 与研究相关的所有数据都包含在文章中或作为补充信息上传。数据、分析方法和研究材料可应合理要求提供给想要重现结果或重复程序的其他研究人员。[1]:/lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT02138695&atom=%2Fheartjnl%2F107%2F23%2F1862.atom 与研究相关的所有数据都包含在文章中或作为补充信息上传。数据、分析方法和研究材料可应合理要求提供给想要重现结果或重复程序的其他研究人员。[1]:/lookup/external-ref?link_type=CLINTRIALGOV&access_num=NCT02138695&atom=%2Fheartjnl%2F107%2F23%2F1862.atom
