Hyaluronic acid(HA),a linear glycosaminoglycan polymer,is an inherent carbon source for gut microbiota and is capable of mitigating host inflammation by modulating gut *** length of hyaluronan can range from an oligomer to an extremely long-form up to millions of Daltons,and its biological functions depend on its molecular mass[1,2].Presently,the precise mechanisms through which HA of varying molecular weights alleviates inflammation by modulating the gut microbiota remain unclear[3].

目的本研究旨在描述不同左心房容积对肺静脉隔离时贴靠压力分布的影响，以更好指导导管贴靠，改善消融策略。方法连续人选2016年8—12月在阜外医院心律失常中心首次接受射频消融治疗的心房颤动（房颤）患者33例，根据患者术前超声心动图和术中三维解剖图按左心房大小分成两组：左心房增大组[左心房容积（155±19）cm3，左心房内径（46±10）mm]和左心房正常组[左心房容积（106±19）cm3，左心房内径（36±5）mm]。采用压力感知导管，关闭压力显示窗口后进行肺静脉隔离。术者根据局部电位大小、阻抗、x线透视及三维导航判断贴靠满意后，在Vistag模式下进行消融，记录心房与导管的贴靠压力（CF）和压力时间积分（FTI）。术后根据左、右肺静脉解剖特点分析各部位压力特征。CF〈10g为贴靠不佳，CF≥10g为贴靠良好。结果在33例房颤患者中共记录3325个点，CF平均（13±9）g。其中，左心房增大组的压力显著低于左心房正常组，差异有统计学意义[（12±5）g对（14±4）g，P〈0．001]。两组最小平均cF值均出现在左心耳一左上肺静脉嵴部[左心房增大组为（4±3）g，左心房正常组为（7±5）g]和左下肺静脉前壁（左心房增大组（5±3）g，左心房正常组（8±4）g]。左心房增大组和正常组导管贴靠不良（CF〈10g）的位置均最常见于左心耳一左上肺静脉嵴部和左下肺静脉前壁（P〈0．001），其次为右上肺静脉前壁和后壁（P〈0．001）。结论左心房容积影响房颤导管消融时的贴靠压力，术者应重视实时监测贴靠压力，以改善导管贴靠，提高消融效率。
