Intracardiac echocardiography improves lesion quality and ablation efficiency of pulmonary vein isolation in atrial fibrillation patients: a propensity score-matched analysis.
Article in Frontiers in cardiovascular medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 2 of them syntheses that pooled it.
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: Pulmonary vein isolation (PVI) is a cornerstone of catheter ablation for atrial fibrillation (AF). Intracardiac echocardiography (ICE) offers real-time imaging that may enhance procedural outcomes compared to traditional x-ray guidance. This study evaluates the impact of ICE on PVI lesion quality and efficiency using a novel Ablation Index Functional Validation (AIFV) system. Methods: This single-center, retrospective, matched cohort study included AF patients undergoing catheter ablation between June 2022 and June 2023 at The Third Affiliated Hospital of Nanjing Medical University. Patients were grouped based on ICE use (ICE vs. No-ICE), with intraoperative data recorded via the VisiTag system and analyzed by AIFV. Propensity score matching (1:1) was applied to compare procedural efficiency and lesion quality (primary endpoints) and AF recurrence (secondary endpoint) between groups. Results: Of 126 patients enrolled (61 ICE, 65 No-ICE), 46 matched pairs were analyzed. PVI was achieved in all cases without severe complications. The ICE group demonstrated significantly shorter total PVI time [2,819 s (2,565 s, 2,953 s) vs. 3,153 s (2,696 s, 3,831 s), Conclusion: ICE enhances the quality of lesions and the ablation efficiency of PVI in AF patients, as shown by the AIFV system.
