A 31-year-old woman underwent radiofrequency catheter ablation of a concealed left posteroseptal accessory pathway associated with a coronary sinus diverticulum. The patient had previously undergone unsuccessful catheter ablation of the posteroseptal region of the mitral annulus. Coronary sinus venography revealed the presence of the diverticulum near the ostium. An electrogram in the neck of the diverticulum showed the shortest ventriculoatrial conduction time and a large accessory pathway potential during atrioventricular reciprocating tachycardia. The pathway was successfully ablated within the neck of the diverticulum. The findings in this case underscore the importance of coronary sinus venography before ablation.
一名31岁女性接受了与冠状静脉窦憩室相关的隐匿性左后间隔旁道的射频导管消融术。该患者此前曾接受二尖瓣环后间隔区域的导管消融术，但未成功。冠状静脉窦造影显示在窦口附近存在憩室。憩室颈部的心电图显示在房室折返性心动过速期间心室房传导时间最短且有大的旁道电位。该旁道在憩室颈部被成功消融。该病例的发现强调了消融前冠状静脉窦造影的重要性。
