Beyond the Pulmonary Veins: The Influence of Pulsed Field Ablation on the Superior Vena Cava.

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
Background: Pulsed field ablation (PFA) selectively ablates myocardial tissue while minimizing damage to surrounding structures. However, its effects on the superior vena cava (SVC) during right superior pulmonary vein (RSPV) isolation remain unclear. Objective: This study aimed to assess the impact of PFA on the SVC and determine whether anatomical proximity contributes to conduction delay or isolation. Methods: This prospective, single-center observational study analyzed 15 patients with paroxysmal atrial fibrillation (AF) who underwent PFA at our institution between December 2024 and February 2025. A 12-F multipolar PFA catheter (FARAWAVE) was used. The shortest RSPV-SVC distance was measured using preprocedural contrast-enhanced CT and intraprocedural electroanatomic mapping. Results: Among the 15 patients, 10 (67%) exhibited PFA-induced conduction abnormalities in the SVC, including conduction delay or partial isolation. Partial SVC isolation was observed in seven patients (47%), with three (20%) developing SVC-originating AF that required additional SVC ablation. The shortest RSPV-SVC distance on CT was significantly shorter in the impact group (6.25 ± 1.7 mm) than in the nonimpact group (9.7 ± 2.0 mm; Conclusion: PFA for RSPV isolation can cause SVC conduction abnormalities, with anatomical proximity as a key determinant. Preprocedural CT assessment may predict unintentional SVC involvement, which may alter arrhythmogenicity. Further studies are needed to assess long-term clinical implications.
