To our knowledge, prograde access to the left ventricle to perform a left-sided AV node (AVN) ablation has not been reported. We present the case of a patient with Noonan's syndrome and supravalve aortic stenosis who required aortic valve replacement with a mechanical valve. Due to chronic atrial fibrillation, a transvenous pacing system was implanted and transcatheter radiofrequency ablation of the AVN was performed. Attempts at right-sided AVN ablation were unsuccessful. Due to the presence of the mechanical aortic valve, a left-sided AVN ablation was performed successfully using the transseptal approach. The patient died suddenly 6 months after the procedure, and the histologic study of the heart is reported.
据我们所知，尚未有经正向途径进入左心室进行左侧房室结（AVN）消融的报道。我们报告一例患有努南综合征和瓣上主动脉狭窄的患者，该患者需要植入机械瓣膜进行主动脉瓣置换。由于慢性心房颤动，植入了经静脉起搏系统并进行了经导管房室结射频消融。右侧房室结消融尝试未成功。由于存在机械主动脉瓣，采用经房间隔途径成功进行了左侧房室结消融。患者在手术后6个月突然死亡，并报告了心脏的组织学研究结果。
