[Ten questions about cardiac sarcoidosis].

Abstract

Cardiac sarcoidosis is a rare but potentially life-threatening condition characterized by the formation of non-caseating granulomas in the myocardium. Clinical manifestations range from asymptomatic forms to atrioventricular blocks, ventricular arrhythmias, heart failure, and sudden cardiac death. Diagnostic work-up requires a multimodality approach combining advanced imaging, clinical criteria, and, when possible, histological confirmation. Immunosuppressive therapy remains the cornerstone of treatment, aimed at suppressing myocardial inflammation and preventing irreversible damage. Risk stratification for sudden cardiac death is crucial, and cardiac implantable electronic devices play a key role in selected patients. This review, structured in ten clinical questions, provides an overview of the epidemiology, clinical presentation, diagnostic criteria, differential diagnosis, therapeutic strategies, and risk stratification of cardiac sarcoidosis, in light of the most recent international guidelines and consensus documents.
