JACC:新型针管式导管消融方法治疗难治性室性心律失常

2019-04-04 不详 MedSci原创

导管消融术对大部分药物难治性室性心律失常(VA)是有效的,然而对于部分异位起搏点位于心肌深处的VA来说,常规的心内膜和心外膜方法效果不佳,这类病人尚无有效治疗方法。本研究的目的旨在评估一种能够瞄准深部心律失常位点的新型可伸缩的27G针管的安全性和可行性。本研究纳入了31例之前至少接受过一次失败的导管消融术的持续性室性心律失常患者,对其进行了新型针管式消融,经过平均每个患者15针治疗后,73%的VT

导管消融术对大部分药物难治性室性心律失常(VA)是有效的,然而对于部分异位起搏点位于心肌深处的VA来说,常规的心内膜和心外膜方法效果不佳,这类病人尚无有效治疗方法。本研究的目的旨在评估一种能够瞄准深部心律失常位点的新型可伸缩的27G针管的安全性和可行性。

本研究纳入了31例之前至少接受过一次失败的导管消融术的持续性室性心律失常患者,对其进行了新型针管式消融,经过平均每个患者15针治疗后,73%的VT患者至少消除了一个异味心律失常位点,5例非持续性心律失常患者中4例出现周围性心律失常。经过平均6个月时间的随访,48%的患者无反复性的心律失常,另外19%的患者有所缓解。操作相关的并发症包括一例心包积液和非致死性的左心室起搏导联移位。

研究结果显示,对于药物和常规导管消融难治性室性心律失常患者,该新型针管式消融方法可改善患者预后,且风险可接受。
