Utilizing the novel AI-guided STAR Apollo™ Mapping System in complex redo-ablations: a case report of successful catheter ablation in a patient with persistent left superior vena cava.

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: Persistent left superior vena cava (PLSVC) can both initiate and perpetuate atrial fibrillation (AF) and poses several challenges to catheter ablation procedures. Novel mapping technologies offer promising potential to these complex patients. We present the first recorded case of artificial intelligence guided pulsed field ablation (PFA) in persistent AF with PLSVC. Case summary: A 70-year-old patient with PLSVC and persistent AF underwent a third-repeat catheter ablation. A three-dimensional geometry of the atria was generated, and STAR Apollo Mapping was used to identify target substrates [early sites of activation (ESAs) and repetitive pattern of activation STARbursts] in real time. Two ESAs were identified in the left atrium (LA) and three in the right atrium; all of these were targeted. Ablation in the PLSVC that overlaid an LA septal ESA terminated AF to sinus rhythm. Remapping confirmed pulmonary vein isolation and exit block, and no further arrhythmias were inducible. There were no procedural complications; the patient was discharged the same day. Discussion: STAR mapping aided identification of alternative ablation targets that would be challenging to identify using classical electro-anatomical mapping alone. This case demonstrates a novel use of this technology in improving procedural outcomes for complex AF patients.
