Influence of ablation index on the incidence of cardiac tamponade complicating pulmonary vein isolation.
Article in Herz, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis 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
backgroundCardiac tamponade (CT) complicating pulmonary vein isolation (PVI) for atrial fibrillation (AF) is a complication that can increase morbidity and mortality. Radiofrequency energy is a known cause of CT. Ablation Index (AI) is a novel ablation quality marker. We hypothesized that use of AI reduces the incidence of CT.
methodsAll AF procedures between 10/2014 and 06/2019 were included. Three ablation groups were defined: group A, RF ablation with non-contact force (CF) catheter; group B, RF ablation with CF catheter; and group C, RF ablation with CF catheter using AI. All episodes of CT were analyzed.
resultsIn total, 1222 consecutive AF patients underwent PVI. Group A consisted of 100 (8%) procedures, while group B included 432 (35%) procedures and group C 690 (57%) procedures. The overall risk for CT in all patients was 2.1% (26/1222). The risk in group A was 2.9% (3/100), in group B 2.5% (11/432), and in group C 1.7% (12/690), including all 1222 patients in the analysis (p < 0.05). Univariate analysis identified no further specific predictors for CT. With the exception of one patient (1/26; 3.8%), who needed surgical treatment, all CT could be successfully drained.
conclusionsIn a high-volume center, the use of AI decreased the risk of CT in patients undergoing RF ablation for AF by 32%.
