Conclusion
A 3830 pacemaker lead can be used to deliver RF and to create deep ablation lesions, with clinical relevant size. The 3830 lead is widely available, and its employment is increasing, making its use for deep ablation purposes appealing. This opens a path to attain deep septal foci (LV summit) or epicardial (vein of Marshall) structures, using standard 4F pacemaker leads, 2F small EP catheters or isolated guidewires.
