We describe one rare case of successful ablation of a right epicardial accessory pathway (AP) via the right ventricular diverticulum in a patient with Wolff-Parkinson-White syndrome.
A 42-year-old woman was referred to the hospital for a catheter ablation of Wolf-Parkinson-White syndrome. The earliest activation was shown to be present in the region of the tricuspid annulus. However, ablation had no effect on the AP.
We decided to do a selected angiography, in which a big diverticulum near the right tricuspid annulus was shown to be present. Ablation in this region successfully repressed the AP without any recurrences within a follow-up period of 12 months.
The ventricular diverticulum-mediated AP is a novel variant of pre-excitation. It can serve as an anatomical substrate of supraventricular tachycardia, and can be ablated endocardially using an irrigation tip catheter within the diverticulum.
我们描述了一例通过右心室憩室成功消融右侧心外膜旁路（AP）的罕见病例，该患者患有 Wolff-Parkinson-White 综合征。
一名 42 岁女性因 Wolff-Parkinson-White 综合征被转诊至医院进行导管消融。最早的激活显示存在于三尖瓣环区域。然而，消融对 AP 没有影响。
我们决定进行选择性血管造影，显示在右三尖瓣环附近存在一个大憩室。在这个区域进行消融成功地抑制了 AP，在 12 个月的随访期间没有复发。
心室憩室介导的 AP 是预激的一种新变体。它可以作为室上性心动过速的解剖学基础，并可使用憩室内的灌流尖端导管进行心内膜消融。
