Abstract

OBJECTIVE

To present the authors' experience of Mahaim-type accessory pathways (MAPs), focusing on anatomic localizations.

METHODS

Data from consecutive patients who underwent electrophysiological study (EPS) for MAP ablation in two tertiary centres, between January 1998 and June 2020, were retrospectively analysed.

RESULTS

Of the 55 included patients, 27 (49.1%) were male, and the overall mean age was 29.5 ± 11.6 years (range, 12-66 years). MAPs were ablated at the tricuspid annulus in 43 patients (78.2%), mitral annulus in four patients (7.3%), paraseptal region in three patients (5.5%), and right ventricle mid-apical region in five patients (9.1%). Among 49 patients who planned for ablation therapy, the success rate was 91.8% (45 patients).

CONCLUSION

MAPs were most often ablated at the lateral aspect of the tricuspid annuli, sometimes at other sides of the tricuspid and mitral annuli, and infrequently in the right ventricle. The M potential mapping technique is likely to be a useful target for ablation of MAPs.

摘要

目的

介绍作者在 Mahaim 型旁路（MAP）方面的经验，重点介绍解剖定位。

方法

回顾性分析了 1998 年 1 月至 2020 年 6 月期间在两个三级中心因 MAP 消融而行电生理研究（EPS）的连续患者的数据。

结果

在 55 名纳入患者中，27 名（49.1%）为男性，总体平均年龄为 29.5±11.6 岁（范围 12-66 岁）。在 43 名患者（78.2%）的三尖瓣环处消融了 MAP，在 4 名患者（7.3%）的二尖瓣环处、3 名患者（5.5%）的间隔区域处和 5 名患者（9.1%）的右心室中隔区处消融了 MAP。在 49 名计划进行消融治疗的患者中，成功率为 91.8%（45 名患者）。
