Spontaneous Remission Without Steroid Therapy in Isolated Cardiac Sarcoidosis with Severe Left Ventricular Systolic Dysfunction.

ABSTRACT

Spontaneous remission is often observed in extracardiac cases of sarcoidosis, such as skin sarcoidosis. However, for cardiac sarcoidosis (CS), the prognosis is unfavorable. Although corticosteroids are the first-line treatment for CS, data regarding the natural history of isolated CS are limited. We describe a rare case of isolated CS with severe left ventricular systolic dysfunction that improved without steroid therapy.
