Abstract

We report a case of a malignant right free wall AP that showed very rapid conduction during atrial fibrillation. The accessory pathway was attached to from the right atrial appendage to the right ventricle. Catheter ablation from an endocardial approach was met with limited success. Epicardial mapping of the atrial insertion site was achieved via a subxiphoid pericardial puncture. Long-term success was noted after ablation was performed in the epicardial space at the site of the tightest VA interval.

摘要

我们报告一例右侧游离壁恶性房室旁道病例,该旁道在房颤时显示出非常快速的传导。该旁道附着于右心耳至右心室。经心内膜途径进行导管消融效果有限。通过剑突下心包穿刺实现了心房插入部位的心外膜标测。在心外膜间隙中VA间期最窄处进行消融后取得了长期成功。
