Sarcoidosis cardíaca: descripción de tres casos

Sarcoidosis is a multisystemic disease of unknown etiology that may affect any organ in the body. The prevalence of sarcoidosis varies widely in different countries and populations. Several reports have suggested that cardiac involvement is associated with adverse outcomes. There are only a few case reports of cardiac sarcoidosis in Latin America and there is no clear agreement regarding the diagnostic and therapeutic aspects of this disease. We describe three case reports of cardiac sarcoidosis with their corresponding clinical, electrocardiographic and imaging characteristics, the histopathological findings of endomyocardial biopsy in two cases, and the clinical course during follow-up.
