研究目的:

环肺静脉消融术(circumference pulmonary vein isolation,CPVI)是房颤射频消融治疗的标准术式,但长程持续性房颤(long-standing persistent atrial fibrillation,LPAF)患者左房扩大、单纯CPVI治疗后房颤复发率高,CPVI联合左房后壁电隔离术(circumference pulmonary vein isolation associated with left atrial posterior wall electric isolation,CPVI-LAPWI)基于CPVI发展而来。本中心通过探讨对LPAF的患者行CPVI-LAPWI治疗的有效性,指导未来LPAF患者治疗指南方向。  

Objectives of Study:

Using circumference pulmonary vein isolation associated with left atrial posterior wall electric isolation technique to evaluate outcomes in patients with long-standing persistent atrial fibrillation

药物成份或治疗方案详述:

术前服用抗凝药(华法林 控制INR 2-3之间;达比加群 110mg bid;利伐沙班 15mg qd)治疗,完善经胸超声明确左房大小,完善经食道超声明确左心房有无血栓及有无严重心脏结构异常。术中利多卡因局麻,穿刺双侧股静脉,左腿放置6F、7F短鞘(Bard, Lowell, MA),X线下放置冠状窦电极;右腿放置长鞘(SL1, St. Jude),使用房间隔穿刺针刺房间隔,放置大头及pentaray至左心房。在Carto系统(CARTO, Biosense Webster)下行左房建壳,在35W、43度、盐水模式(盐水2ml/min、消融状态下17ml/min)下行CPVI,其中消融左房前壁时AI(Ablation index,射频消融指数) 500、左房后壁时AI 400,后行左房后壁顶部线及底部线线性隔离,其中消融顶部线时AI 450、下壁线时AI 400。消融后若房颤持续,予患者力月西2mg后电复律,并于窦律下用pentaray行精细高密度标测确认消融线完全阻滞并标测后壁内最早激动点。若后壁内电激动标测没有明确早的部位,选择高电压区域大电位开始消融(图5 CPVI-LAPWI后选择高电压区域大电位开始消融),再次用pentaray精细高密度标测确认后壁隔离。术中予患者低分子肝素抗凝,维持ACT 300-350。术后口服奥美拉唑1月,胺碘酮3月,抗凝药6月。
