BACKGROUND
Pulsed-field ablation using annular or petal-shaped catheters had been proven to be effective for achieving electrical isolation of pulmonary veins in patients with atrial fibrillation. However, the utilization of linear pulse-field power for treating atrial flutter has yet to been documented.
CASE SUMMARY
In this report, we present a case involving the successful treatment of tricuspid isthmus-dependent atrial flutter treated with a linear pulsed-field catheter. The patient, a 71-year-old male, presents with an electrocardiogram indicating atrial flutter. Subsequent electrophysiological examination reveals typical atrial flutter that is dependent on the cavo-tricuspid isthmus (CTI). This condition is successfully terminated through the application of linear pulsed-field ablation.
DISCUSSION
This case represents a pioneering instance of CTI-dependent atrial flutter ablation utilizing linear pulse-field power. The innovative approach not only effectively treats the patient but also serves as a valuable reference for future applications of linear treatment with pulsed-field ablation.
背景
已证实使用环形或花瓣形导管进行脉冲场消融对于实现心房颤动患者肺静脉的电隔离有效。然而，利用线性脉冲场能量治疗心房扑动尚未见文献报道。
病例摘要
在本报告中，我们呈现了一例使用线性脉冲场导管成功治疗三尖瓣峡部依赖性心房扑动的病例。该患者为一名71岁男性，心电图显示为心房扑动。随后的电生理检查发现典型的依赖于腔静脉 - 三尖瓣峡部（CTI）的心房扑动。通过应用线性脉冲场消融成功终止了这种情况。
讨论
该病例代表了利用线性脉冲场能量进行CTI依赖性心房扑动消融的开创性实例。这种创新方法不仅有效治疗了患者，也为未来脉冲场消融线性治疗的应用提供了有价值的参考。
