Efficacy and safety of catheter ablation for atrial arrhythmias in patients with cardiac amyloidosis: a systematic review and meta-analysis.
Review in Archives of medical sciences. Atherosclerotic diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: Cardiac amyloidosis (CA) is a restrictive cardiomyopathy characterized by amylin deposits in the heart muscle. While the prevalence of atrial arrhythmias in CA is high, the data regarding the outcomes of catheter ablation in these patients are limited. This study aimed to elucidate the safety and efficacy of catheter ablation for treating atrial arrhythmias in patients with CA. Methods: We conducted a comprehensive literature search across PubMed, Embase and Cochrane from inception till January 2024 for randomized control trials and observational studies reporting catheter ablation (cryoablation or radiofrequency ablation) for the treatment of atrial arrhythmias (AAs) (atrial flutter, atrial fibrillation, atrial tachycardia) in patients with cardiac amyloidosis. The primary outcome of interest was pooled recurrence rate. The secondary outcomes were re-ablation rate and all-cause mortality. All data were analyzed using the Hedges-Olkin random-effects model and presented as percentage proportions. Results: A total of 9 cohort studies ( Conclusions: The high rates of recurrence, need for re-ablation, and associated mortality highlight the need for better patient selection. Prospective and randomized controlled data are needed to further study the outcomes of catheter ablation in these patients.
