Impact of the dispersive patch placement on dissipated power in radiofrequency ablation for pulmonary vein isolation via a virtual patient study.

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
Radiofrequency ablation (RFA) is a minimally invasive technique for treating arrhythmias by interrupting abnormal electrical signals in the heart. Through a catheter tip, it delivers an alternating current that flows through the heart muscle tissue and the blood to a dispersive patch on the patient's skin. This study aims to test the hypothesis that the placement of the dispersive patch affects the efficacy and safety of RFA. By optimizing the patch position, the procedure could be made more effective and less risky for patients. A 3D in-silico model, based on patient imaging data, was developed to examine the effects of dispersive patch (DP) positioning on electric field distribution within cardiac tissue and the torso during RFA. We conducted 80 computer simulations using a CT-segmented torso model, exploring various DP and electrode configurations while applying standard (25 W) and high (90 W) power settings. For each configuration, we assessed the effectiveness of the DP in delivering power to cardiac tissue near the electrode. The main finding indicates that DP efficacy is significantly influenced by the current delivered to cardiac tissue. Notably, using an anterior patch during ablation proved more effective for the posterior left atrium compared to a posterior patch.
