AB  - A young-male underwent radiofrequency (RF) ablation of ventricular premature 
      contractions (VPCs) of over 30,000/day and the morphology exhibited left bundle 
      branch block and a superior axis, which indicated the VPCs originated from the 
      inferior portion of the right ventricle (RV). While the PENTARAY catheter was 
      placed under the tricuspid valve (TV), the earliest potential, which preceded the 
      QRS onset by 34 ms, was recorded. Pace mapping there presented a very similar QRS 
      morphology to the target VPC. However, the radiofrequency (RF)-catheter could not 
      be placed under the TV even when a deflectable sheath was used, because the 
      deflectable curve of the RF-catheter was larger than that of the PENTARAY. An 
      over-the-vale RF application was not effective, so the trans-jugular approach 
      with a deflectable sheath was indicated. The tip of the sheath was placed at a 
      higher portion of the RV cavity to maintain an adequate distance for the 
      RF-catheter tip to be deflected and placed under the TV. With this maneuver, the 
      tip of the RF-catheter was successfully placed under the TV, which was confirmed 
      by intracardiac ultrasound. Small atrial potentials and larger ventricular 
      potentials could be recorded from the distal tip of the RF-catheter, which might 
      indicate that the tip was placed at the TV annulus. An RF application at that 
      site permanently abolished the VPC. Placing the tip of the RF-catheter under the 
      TV by the femoral approach is very difficult in some cases. The trans-jugular 
      approach with a deflectable sheath is one option for arrhythmias from the TV.
