The case of a patient with a symptomatic Wolff-Parkinson-White syndrome undergoing attempted radiofrequency catheter ablation of a posteroseptal accessory pathway is described. Coronary sinus venography revealed the presence of a diverticulum attaching near the os. The electrogram recorded from a catheter placed in the narrow neck of the diverticulum revealed a short atrioventricular time during sinus rhythm. The pathway was easily ablated using radiofrequency energy applied in the neck of the diverticulum, after multiple failed attempts at catheter ablation from the endocardial surface of the posteroseptal space. Our report emphasizes the importance of searching for a coronary venous diverticulum in all patients with posterior accessory pathways undergoing catheter ablation.
本文描述了一例有症状的预激综合征患者,尝试对其后间隔旁道进行射频导管消融的病例。冠状静脉窦造影显示在窦口附近有一个憩室。置于憩室狭窄颈部的导管记录的心电图显示窦性心律时房室时间短。在多次尝试从后间隔空间的心内膜表面进行导管消融失败后,使用施加于憩室颈部的射频能量很容易地消融了该旁道。我们的报告强调,在所有接受导管消融的后间隔旁道患者中寻找冠状静脉憩室的重要性。
