Cardiac sarcoidosis: a diagnostic and therapeutic challenge

Abstract

Objective: Cardiac involvement in sarcoidosis can present in various ways, with atrioventricular (AV) block and ventricular arrhythmias being the most common signs. Because of initial non-specific findings, diagnosis can be a challenge. Very few data can support treatment decisions as cardiac manifestations of this systemic disorder are rare.

Methods and results: We reviewed current guidelines, cohort studies, and expert opinions concerning diagnosis and treatment of cardiac sarcoidosis.

Conclusions: Longitudinal follow-up studies are necessary to improve the diagnostic process and risk stratification of cardiac sarcoidosis. The optimal dose of steroids, indications for internal cardioverter-defibrillator (ICD), and technique and optimal timing of ablation are still under debate.
