Gastroparesis as a potential complication of pentaspline pulsed field ablation without endoscopic esophageal injury.

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
backgroundPulsed field ablation (PFA) is a new nonthermal, ablation modality for pulmonary vein isolation (PVI) that is cardiac tissue selective. Compelling acute and long-term success rates and good safety features have been reported using a pentaspline PFA catheter. Thus far, no atrio-esophageal fistula (AEF) related to PFA has been reported. However, this fatal complication is rare and endoscopically detected esophageal lesions (EDEL) may serve as a more sensitive instrument to document esophageal safety. This study aimed to evaluate the esophageal safety of the Farapulse™ PFA system by systematically using upper endoscopy post-ablation in a large, single-center cohort.
methodsPatients with symptomatic atrial fibrillation (AF) underwent PVI using the pentaspline PFA system. Additional left atrial posterior PFA application was used in some cases. All patients underwent esophageal endoscopy within 1 day post-ablation. Follow-up visits occurred 3 and 12 months post-procedure. The patients had 48 h-Holter monitoring performed before each visit.
resultsConsecutive, symptomatic AF patients (n = 228, 87.6% paroxysmal) were enrolled. The patients were relatively young (age 59.4 ± 11.7 years), 67.4% male, and had a normal mean left ventricular function of 60 ± 8%. Mean left atrial diameter was 41 ± 4 mm. All PVs were successfully isolated. The procedure time was 55 ± 11 min, fluoroscopy duration was 7 ± 3 min, and the median dose area product was 563 ± 410 cGy cm
conclusionsThe lack of EDEL post-PVI using the pentaspline PFA-catheter in this large AF cohort highlights the esophageal safety of this method. Gastroparesis was observed in a small minority, but relationship with PFA is still to be determined.
