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

Background: Arrhythmogenic cardiomyopathy (ACM) is an inherited disease characterized by fibrofatty replacement, most often involving the right ventricle but potentially affecting the left or both ventricles. It predisposes to severe ventricular arrhythmia (VA). Differentiating ACM from athlete's heart remains difficult, particularly in gene-elusive patients. Implantable cardioverter-defibrillators (ICDs) and catheter ablation are key therapeutic options. Epicardial ablation may be required for VA circuits inaccessible in an endocardial approach, but data on its feasibility in patients with extravascular ICD (EV-ICD) featuring a retrosternal lead is scarce. Case summary: A 42-year-old male athlete was admitted for syncope due to sustained ventricular tachycardia (VT) during exertion. Cardiac magnetic resonance imaging (CMR) showed a dilated right ventricle (RV) with wall akinesia and fibrosis involving the RV outflow tract. Genetic testing was negative. The diagnosis of borderline gene-elusive ACM was made. An EV-ICD was implanted for secondary prevention. Recurrent sustained VT prompted endocardial and epicardial ablation, which was feasible and successful, but radiofrequency energy application was hampered close to the retrosternal lead due to electromagnetic interference. Conclusion: This case highlights the diagnostic and therapeutic challenges of ACM in athletes. Epicardial ablation is feasible even with an EV-ICD, although electromagnetic interference may complicate ablation near the lead. High-level endurance exercise can induce ACM-like remodelling, creating phenotypic overlap with gene-elusive ACM. Early recognition, tailored ablation strategies, and appropriate device therapy are essential for the management of these patients.
