Pulsed field ablation of ventricular arrhythmias arising from intracavitary structures: insights from a clinical case series.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionPremature ventricular complexes (PVCs) from intracavitary structures, such as papillary muscles and the moderator band, can be challenging to treat. Pulsed field ablation (PFA) offers a novel strategy for treating these arrhythmias.
methodsBetween 2023 and 2024, three patients with intracavitary PVCs (two with PVC-mediated ventricular fibrillation) underwent PFA at a tertiary referral centre. Electroanatomic mapping was performed and, with intracardiac echocardiography (ICE) guidance, PFA was delivered using a pentaspline Farapulse catheter, with adjuvant radiofrequency (RF) ablation as needed.
resultsAll patients had successful abolition of PVCs. PFA delivery was feasible and safe, with excellent success despite prior RF ablation failures though one patient required adjuvant RF ablation. The only complication was a persistent right bundle branch block (RBBB) after PFA delivery to the moderator band. Follow-up showed significant reductions in PVC burden and no further ventricular fibrillation (VF) episodes. The mean procedural duration was 153.67 ± 31.71 min, and the mean fluoroscopy time was 14.38 ± 6.74 min.
conclusionThis is a preliminary proof of concept report for ablation of PVCs from intracavitary structures, warranting further validation studies.
