Aim 

To report the Italian data deriving from the European Society of Cardiology-EURObservational Research Program atrial fibrillation ablation long-term registry.

Methods and results 

Ten Italian centers enrolled up to 50 consecutive patients undergoing atrial fibrillation ablation. Of the 318 patients included, 5 (1.6%) did not undergo catheter ablation, 1 had ablation partially done and 62 were lost at 1-year follow-up. Women were less represented (23.6%) and the median age was 60.0 years. A total of 195 patients (62.3%) suffered paroxysmal atrial fibrillation, whereas only 9 (2.9%) had long-standing persistent atrial fibrillation. Most Italian patients (92.3%) were symptomatic but suffering fewer symptomatic events than patients enrolled in other countries (median of two events in the month preceding the ablation vs. three, respectively; P < 0.0001). The main finding of the study is that the success rate at 1 year, with and without antiarrhythmic drugs, was 76.4%, consistently with other participating countries (73.4%). This result was obtained however, with a significantly lower prevalence of 1-year adverse events (7.3 vs. 16.6%, P < 0.0001). Procedure duration and fluoroscopy total time resulted as being shorter in Italy (145 vs. 160, P = 0.0005 and 16.9 vs. 20.0 min, P = 0.0018, respectively); however, the radiation dose per BSA was greater (37.5 vs. 26.0 mGy/cm², P = 0.0022).

Conclusion 

The demographic characteristics of patients undergoing atrial fibrillation ablation are similar to those reported in other countries. The success rate in Italy is consistent with those in other countries, whereas the complications rate is lower.

长期房颤消融ESC-EHRA EORP AFA LT注册表：意大利的住院和1年随访结果。

目标 

报告源自欧洲心脏病学会-EURObservational研究计划房颤消融长期登记的意大利数据。

方法与结果 

意大利的10个中心招募了多达50位连续的房颤消融患者。纳入的318例患者中，有5例（1.6％）未进行导管消融，其中1例部分切除，62例在1年随访中丢失。妇女的比例较低（23.6％），中位年龄为60.0岁。共有195例患者（62.3％）发生阵发性房颤，而只有9例（2.9％）患有长期持续性心房颤动。与其他国家的患者相比，大多数意大利患者（92.3％）有症状，但症状事件较少（消融前一个月发生两次事件的中位数，分别为三例；P<0.0001）。该研究的主要发现是，有或没有抗心律失常药物的1年成功率是76.4％，与其他参与国一致（73.4％）。然而，获得的结果是1年不良事件的患病率显着降低（7.3比16.6％，P <0.0001）。在意大利，手术时间和荧光检查总时间较短（分别为145比160，P = 0.0005和16.9比20.0 min，P = 0.0018）；但是，每个BSA的辐射剂量更大（37.5对26.0 mGy / cm ²，P = 0.0022）。

结论 

房颤消融患者的人口统计学特征与其他国家/地区相似。意大利的成功率与其他国家相同，但并发症发生率较低。
