Left Atrial Intracardiac Echocardiography to Assist Zero Fluoroscopy Pulse Field Atrial Fibrillation Ablation-A Beginner's Guide.

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) has emerged as a novel energy source for the management of atrial fibrillation (AF), offering improved tissue selectivity and a better safety profile. Although fluoroscopy has traditionally guided catheter positioning, the integration of intracardiac echocardiography (ICE), particularly from a left atrial (LA) vantage point, presents an opportunity for real-time visualization and enhanced procedural precision. In this paper, we describe a workflow for LA-ICE-guided PFA, without using fluoroscopy, and present preliminary data from our centre. Methods: All patients who underwent PFA for AF since December 2024 were screened, and those who underwent LA-ICE-guided ablation were included in the study. After patients provided informed consent, procedures were performed under general anesthesia with muscle relaxants to minimize stimulation of extracardiac muscles. Results: LA-ICE-guided PFA was performed in 100 consecutive patients with paroxysmal (73%) and persistent (27%) AF at a single centre. Zero-fluoroscopy (ZF) ablation was successfully performed in 28 patients, without any major complications. The challenges encountered during ZF ablation included enlarged atria, thick interatrial septum, venous tortuosity, aortic root aneurysm, and pacemaker leads. Visualizing the FlexCath sheath while crossing the interatrial septum and confirming its position in the left atrium immediately after crossing does require some effort, especially in a dilated left atrium. Conclusions: LA-ICE facilitates ZF-PFA for AF by offering superior visualization of the LA anatomy, continuous monitoring of catheter orientation, precise catheter positioning, and maintenance of catheter-tissue contact.
