Abstract

Catheter ablation of AV conduction with radiofrequency energy can be challenging in the presence of structural abnormalities of the AV junction, either congenitally or after reconstructive surgery. We used transcoronary ethanol to ablate the AV node in a patient with classic tricuspid atresia and refractory intraatrial reentry tachycardia. This approach provides an alternative means of creating complete heart block with catheter-based techniques, when radiofrequency catheter ablation is technically impossible or ineffective.

摘要

在存在先天性或重建手术后房室交界区结构异常的情况下，利用射频能量进行房室传导的导管消融可能具有挑战性。我们对一名患有典型三尖瓣闭锁和顽固性房内折返性心动过速的患者使用经冠状动脉乙醇来消融房室结。当射频导管消融在技术上不可能或无效时，这种方法提供了一种利用导管技术造成完全性心脏传导阻滞的替代手段。
