摘要(Abstract)：

目的总结伴发左心房自发性超声显影(LASEC)的心房颤动(AF)患者导管消融围术期抗凝治疗的方法、疗效及安全性。方法回顾性分析北部战区总医院心内科2018年1—12月行导管消融的AF患者595例,其中经食管超声心动图检出LASEC者147例(LASEC组),无LASEC者448例(无LASEC组)。结果 LASEC组持续性AF比例高于无LASEC组(36.7%比27.0%,P=0.025),左心房(LA)内径大于无LASEC组[(41.4±4.7)mm比(36.8±4.9)mm,P<0.001]。两组术前应用新型口服抗凝药利伐沙班或达比加群酯比例比较,差异均无统计学意义(均P>0.05)。LASEC组术前抗凝时间长于无LASEC组[(17.2±11.2)d比(7.2±7.6)d,P<0.001],术中肝素用量大于无LASEC组[(8925.5±1532.2)U比(8010.2±1473.7)U,P=0.004],平均激活全血凝固时间(ACT)值大于无LASEC组[(333.0±31.3)s比(296.0±27.6)s,P=0.001]。两组围术期均无卒中及重要脏器出血发生。LASEC组及无LASEC组分别随访(8.9±2.7)个月及(9.7±2.8)个月,随访期间出血事件及血栓栓塞事件发生率比较,差异均无统计学意义(均P>0.05)。结论对于接受AF导管消融的LASEC患者,围术期强化抗凝治疗安全有效。
