Description
T Kamakura and colleagues examine, in a 2026 study, lasting effects of pulsed field ablation on the large vein that drains the upper body into the heart. That vein, the superior vena cava, sits close to the right upper lung vein, a routine ablation target. Earlier reports noted the vein's signals slowing or blocking right after treatment.
Among 407 patients treated with three different systems, eighteen returned for a second procedure and had the vein remapped. A new low-voltage patch had appeared in the vein in fourteen of them right after the first ablation. Months later the change persisted in just over half of those cases, especially where the two veins lay closest together. In one patient the patch formed part of a new rhythm circuit.
