目的:描述我国心房颤动（房颤）介入治疗的现况并对医疗质量开展分析。方法:在全国7大区域中分别选取1~3家区域医学中心，按比例随机抽取各中心2017年全年行房颤介入治疗（导管消融术及左心耳封堵术）的住院病历，收集CHAn 2DSn 2-VASc评分记录、导管消融术后抗凝、是否符合左心耳封堵术适应证等情况，并分析当次住院期间介入治疗相关并发症和严重并发症。n 结果:17家中心2017年共行房颤导管消融术10 800例、左心耳封堵术447例。10/17中心房颤导管消融手术量0.05］。左心耳封堵适应证符合率为81.3%（130/160），其中手术量≥20例的中心符合率高于手术量0.05). The coincidence rate of LAAO indication was 81.3% (130/160), and the rate was higher in center performing ≥20 cases than in centers performing<20 cases (84.8% (106/125) vs. 68.6% (24/35),n P<0.05). The complication and severe complication rates of LAAO were 3.1% (5/160) and 1.9% (3/160). The rate of complications in LAAO was higher in center performing<20 cases than in centers performing ≥20 cases (8.6% (3/35) vs. 1.6% (2/125),n P0.05).n Conclusions:Interventional therapy for AF in China is generally standardized and safe. The overall incidence of complications post AF interventional ablation is low, the anticoagulation rate after AF catheter ablation is high, and the adherence rate of LAAO indication is fair. The indicators mentioned above vary widely among centers.
