Description
Panteleimon Papakonstantinou and Gabor Szeplaki reported a repeat ablation case in 2026 using a new pulsed-field catheter. Pulsed-field ablation kills heart tissue with electric pulses rather than heat or cold, sparing nearby structures like the esophagus. Most systems target the lung vein openings. A focal catheter from Boston Scientific can also draw lines and treat wider areas with steady depth.
The case shows isolation of the back wall of the left upper chamber during a redo procedure. Step-by-step applications with few lesions achieved the block. Spacing and predictable depth proved key, the authors note. Such focal use for wall isolation is still off-label and needs more study, they caution.
