The acquisition of good contact force for radiofrequency catheter ablation of ventricular premature complexes (VPCs) originating from the basal septum of the left ventricle (LV) is often difficult. We describe a case of VPCs originating from the basal septum of the LV, which were successfully eliminated by applying radiofrequency at the right atrium (RA) side of the atrioventricular septum (AVS) without causing any significant impairment of atrioventricular conduction because the ablation catheter could obtain better contact force through the RA approach. Moreover, intracardiac echocardiography (ICE) and RA angiography effectively demonstrated the AVS.
对于起源于左心室（LV）基底部间隔的室性早搏（VPC）进行射频导管消融时，常常难以获得良好的接触力。我们描述了一例起源于LV基底部间隔的VPC，通过在房室间隔（AVS）的右心房（RA）侧应用射频成功消除，且未导致任何明显的房室传导损害，因为消融导管通过RA途径可获得更好的接触力。此外，心腔内超声心动图（ICE）和RA血管造影有效地显示了AVS。
