摘要 目的评价新型压力感知导管消融治疗心房颤动(房颤)的临床疗效。方法导管消融治疗的房颤患者81例,依据消融导管使用情况分为压力导管组(使用压力感知导管进行消融术)27例及对照组(使用普通盐水灌注导管进行消融术)54例。评价临床疗效,记录术中肺静脉隔离率、手术时间及X线透视时间,计算肺静脉-左房传导恢复率;压力导管组将环肺静脉消融环分为6个节段,记录每个节段消融导管压力数值,计算各节段总的压力平均值。消融术后患者均随访6个月,比较两组房颤复发率。结果两组肺静脉电隔离率均为100%,两组恢复窦性心律率比较,P﹥0.05。两组手术时间、X线曝光时间、肺静脉-左房传导恢复率比较,P均﹥0.05;环肺静脉消融各节段压力平均值在10 g左右;消融术后6个月,压力导管组房颤复发率低于对照组(11.1%比14.8%,P<0.05)。结论压力感知导管消融治疗能降低房颤患者术后6个月复发率。
