Recurrent myocarditis as a clinical gateway to desmoplakin cardiomyopathy: a case report.

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
Background: Recurrent acute myocarditis is an uncommon clinical scenario that may suggest the presence of an underlying genetic cardiomyopathy. Case summary: A 30-year-old woman presented to the emergency department with recurrent acute myocarditis in 2020 and 2022 and presented to the consult with chest pain in 2023. A syndromic diagnostic workup ruled out infectious, autoimmune, and toxic aetiologies. Cardiac magnetic resonance imaging revealed subepicardial and mid-myocardial oedema and fibrosis, predominantly affecting the left ventricle, which was subsequently confirmed by an endomyocardial biopsy showing chronic inflammation and interstitial fibrosis. Genetic testing ultimately identified a pathogenic partial deletion in the desmoplakin cardiomyopathy DSP gene, establishing the underlying cause. Management included antiarrhythmic therapy, genetic counselling, lifestyle modifications, and the implantation of a cardioverter-defibrillator. Discussion: Desmoplakin cardiomyopathy is a genetic disorder that can mimic recurrent myocarditis through inflammatory 'hot phases'. Recognition of this phenotype is essential in patients with recurrent myocarditis, especially when imaging findings show left-dominant fibrosis and arrhythmic features. Early diagnosis has important implications for treatment, prognosis, and prevention of sudden cardiac death.
