Modified intracardiac echocardiography (ICE)-guided transseptal puncture under ablation catheter guidance.
Article in BMC cardiovascular disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundZero-fluoroscopy procedures have become increasingly popular in electrophysiological interventional surgery. As a core technology for achieving zero-fluoroscopy, traditional transseptal puncture (TSP) under intracardiac echocardiography (ICE) guidance has several limitations that hinder its widespread application and further development. This study aims to introduce and evaluate the efficacy and safety of a modified TSP technique developed based on clinical practice, which has the potential to overcome the shortcomings of traditional ICE-guided TSP.
methodsA total of 77 patients who underwent radiofrequency ablation for atrial fibrillation (AF) between March 1, 2022 and February 28, 2023 were enrolled. Among them, 44 patients underwent traditional ICE-guided TSP, and 33 patients underwent modified ICE-guided TSP. The success rate, numbers of puncture attempts, puncture duration, proportion of ideal puncture location and incidence of puncture-related complications were recorded.
resultsThere were no significant differences in baseline characteristics between the two groups. Compared with the traditional group, the modified group had a significantly lower number of puncture attempts (1.25 ± 0.44 vs.1.06 ± 0.24, p = 0.018) and shorter puncture duration (2.52 ± 0.83 vs.3.94 ± 2.15 min, p = 0.001). No significant differences were observed in TSP success rate, proportion of ideal puncture location or incidence of puncture-related complications between the two groups.
conclusionsThis study presents a modified ICE-guided TSP technique using an ablation catheter for guidance. This technique simplifies the operation of the puncture component and eliminates the need for ICE view tracking. It offers advantages including high success rate, favorable safety profile, simple procedural steps, ease of use, and a short learning curve, making it worthy of clinical promotion and application.
