Epicardial location of accessory AV pathways may be responsible for the failure of conventional endocardial radiofrequency catheter ablation. Transcutaneous epicardial instrumentation provides access to the normal pericardium with no need for invasive thoracotomy or thoracoscopy. We report the case of successful epicardial mapping and ablation of a right atrial appendage-ventricular connection using a percutaneous epicardial approach, after repeated failure of endocardial ablation attempts.
房室旁道的心外膜定位可能是导致传统心内膜射频导管消融失败的原因。经皮心外膜器械可进入正常心包，无需进行侵入性开胸手术或胸腔镜检查。我们报告了1例在心内膜消融尝试反复失败后，采用经皮心外膜方法成功进行心外膜标测并消融右心耳 - 心室连接的病例。
