Description
Pranav Bhagirath and colleagues report a 2026 first case of pulsed-field ablation inside and outside the heart in a man carrying an extravascular defibrillator. The 62-year-old had ischaemic heart muscle disease and repeated dangerous rhythms despite drugs and an earlier inner-surface ablation. Epicardial ablation in such device carriers raises access and safety questions, since a lead sits just under the breastbone.
Guided by CT planning and functional mapping, the team targeted a slow-conduction zone on the outer surface with pulsed-field energy plus a little radiofrequency heat. The outer zone and the clinical rhythm were abolished, though a rapid non-clinical rhythm stayed inducible, and the lead was moved to fix noise oversensing. No complications arose and 30-day remote checks showed no rhythm events, backing a workable path for similar patients.
