Abstract

Background: An accurate display of scar-related atrial tachycardia (ATs) is a key determinant of ablation success. The efficacy of ripple mapping (RM) in identifying the mechanism and critical isthmus of scar-related ATs during coherent mapping is unknown.

Methods: A total of 97 patients with complex ATs who underwent radiofrequency catheter ablation at our center between October 2018 and September 2022 were included. ATs was mapped using a multielectrode mapping catheter on the CARTO3v7 CONFIDENCE module. Coherent and RM were used to identify the reentrant circuit.

Results: The mechanisms of 128 ATs were analyzed retrospectively (84 anatomic-reentrant ATs and 44 non-anatomic reentrant ATs). The median AT cycle length was 264 ± 25ms. The correct diagnosis was achieved in 83 ATs (68%) using only coherent mapping. Through coherent mapping plus RM, 114 ATs (84.2%) were correctly diagnosed (68% vs. 89%, p = .019). In non-anatomical reentrant ATs, 81% of the diagnostic rate was achieved by reviewing both coherent and ripple mapping compared to reviewing coherent mapping alone (81% vs. 52%, p = .03). Reviewing coherent mapping and ripple mapping showed a higher diagnostic rate in patients who underwent cardiac surgery than those with Coherent mapping alone (64% vs. 88%, p = .04).

Conclusion: Coherent mapping combined with RM was superior to coherent mapping alone in identifying the mechanism of scar-related ATs post-cardiac surgery and non-anatomic reentrant ATs.

瘢痕相关性房性心动过速相干映射时代波纹映射的价值。

背景：准确显示瘢痕相关房性心动过速（ATs）是消融成功的关键因素。波纹测图（RM）在相干测图过程中识别瘢痕相关房性心动过速的机制和关键峡部的效果尚不清楚：纳入2018年10月至2022年9月期间在本中心接受射频导管消融术的97例复杂AT患者。使用 CARTO3v7 CONFIDENCE 模块上的多电极映射导管对 ATs 进行映射。结果：回顾性分析了 128 例 AT 的机制（84 例解剖型再发性 AT 和 44 例非解剖型再发性 AT）。AT 周期长度的中位数为 264±25 毫秒。仅使用相干映射，83 例 AT（68%）获得了正确诊断。通过相干映射加 RM，114 个 AT（84.2%）被正确诊断（68% vs. 89%，p = .019）。在非解剖再入型 AT 中，同时复查相干图谱和波纹图谱与单独复查相干图谱相比，诊断率提高了 81%（81% 对 52%，p = .03）。在接受心脏手术的患者中，复查相干图谱和波纹图谱的诊断率高于仅复查相干图谱的患者（64% 对 88%，P = .04）：结论：在确定心脏手术后瘢痕相关性自动脉粥样硬化和非解剖性再发性自动脉粥样硬化的机制方面，相干图谱与波纹图谱相结合优于单独使用相干图谱。
