Pulsed-Field Ablation With a Persistent Left Superior Vena Cava: Potential for Transmural Ablation.

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
backgroundA persistent left superior vena cava (PLSVC) is an important source of nonpulmonary vein triggers in patients with atrial fibrillation. However, experience with pulsed-field ablation (PFA) in the presence of a PLSVC is limited. CASE SUMMARY: A 63-year-old man with persistent atrial fibrillation presented for PFA. A previously unrecognized PLSVC was identified. A decapolar catheter was positioned in the PLSVC. During PFA, attenuation of the PLSVC electrograms was observed, consistent with a potentially transmural effect. Given this observation and the lack of preprocedural discussion with the patient, direct ablation within the PLSVC was not undertaken. DISCUSSION: Our case suggests that PFA within the left atrium may affect the adjacent PLSVC and potentially eliminate PLSVC triggers and PLSVC-left atrial connections. TAKE-HOME MESSAGE: PFA lesions within the left atrium may extend in part transmurally to the adjacent PLSVC, potentially obviating the need for direct ablation within the PLSVC and associated risks.
