1 · What the graph read from 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.

2 · The registry

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

backgroundUse of 3-dimensional electroanatomic mapping (3D-EAM) has become a standard when ablating ventricular arrhythmias (VA) in patients with structural heart disease (SHD). Integrating cardiac magnetic resonance imaging (CMR) with 3D-EAM might improve substrate detection and ablation outcomes. Our study aims to evaluate the outcomes of integrating CMR with 3D-EAM for VA ablation in patients with SHD.

methodsA literature search was conducted up to December 2025, focusing on the integration of CMR into ablation procedures in patients with VA and SHD. CMR studies were categorized into CMR-guided (CMR data were merged with 3D-EAM) and CMR-aided (CMR data were used to assist in mapping or procedural approach). The control group was patients who received 3D-EAM alone. Primary endpoint was VA recurrence. Secondary endpoints were procedural success, procedural time, fluoroscopy time, radiofrequency ablation (RF) time, and major procedural-related complications.

resultsA total of 18 studies were included (1,243 participants, mean age 62.7 ± 12.5 years). Both the CMR-guided and CMR-aided had a VA recurrence of 25% and 26%, compared to 51% in 3D-EAM. The CMR-guided showed significantly lower VA recurrence (OR 0.26, 95% CI: 0.17-0.39, I

conclusionThe CMR-guided ablation approach in patients with VA and SHD demonstrated a lower VA recurrence and higher procedural success with comparable safety to 3D-EAM alone.
