Use of a Focal Pulsed Field Ablation Catheter to Target Premature Ventricular Contractions From the Papillary Muscle.

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
The papillary muscles are a common site of origin for premature ventricular contractions (PVCs). Radiofrequency ablation of these PVCs is often challenging due to catheter instability and the inability to penetrate fibrotic tissue, leading to limited clinical success in PVC suppression. In this report, we describe the use of pulsed field ablation (PFA), delivered via a novel focal ablation catheter, to successfully treat papillary muscle PVCs in 2 symptomatic, treatment-refractory patients. Both patients had previously undergone at least 1 failed ablation attempt using conventional radiofrequency catheters but achieved durable suppression or reduction in PVC burden after a limited number of PFA applications. Neither patient experienced complications related to the delivery of PFA energy. Although the safety and efficacy of PFA within the ventricle are still being explored, its rapid energy delivery and ability to penetrate fibrotic tissue may make it uniquely suited for ablation of PVCs originating from papillary muscles.
