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.
