**1. Introduction**

Sarcoidosis is a systemic disease of unknown origin characterized by infiltration of non-necrotizing granulomas. This disease can affect any organ, including the heart. The heart can be involved to a variable extent depending on the area studied [1]. The ACCES study reported about 95% of findings compatible with cardiac involvement [2]. Others report mainly pulmonary involvement. Studies in Japan report cardiac infiltration up to 25% in contrast with the European studies in which the prevalence ranges from 2 to 7% [3].
