摘要(Abstract)：

目的 探讨右心房心房扑动（房扑）患者三尖瓣峡部线消融中可调弯鞘管应用对射频消融疗效的影响。方法 本研究纳入2023年1月至2024年3月首都医科大学附属北京安贞医院行射频消融治疗的房扑患者，分为可调弯鞘管组和普通鞘管组。比较两组射频消融术中的消融时间和消融点数及单次三尖瓣峡部线阻滞率、观察期间三尖瓣峡部线电传导再次连接率。定期门诊随访和电话随访，比较两组房扑临床复发情况。结果 共纳入房扑患者183例，可调弯鞘管组54例，普通鞘管组129例。可调弯鞘管组患者行射频消融治疗术中消融点数明显少于普通鞘管组[（14.0±6.6）个比（17.3±9.2）个，P=0.011]，消融时间明显减少[（9.6±4.2）min比（12.3±7.5）min,P=0.008]，单次消融三尖瓣峡部线双向阻滞率更高（90.7%比72.1%,P=0.006），观察期间三尖瓣峡部线电传导再次连接率更低（1.9%比14.0%,P=0.015），差异均有统计学意义。结论 房扑患者三尖瓣峡部线消融采用可调弯鞘管可提高射频消融效率，提高三尖瓣峡部线单次双向阻滞成功率，降低观察期间三尖瓣峡部线电传导再次连接率。
