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

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.

Coexistence of Spontaneous Coronary Artery Dissection, Takotsubo Cardiomyopathy, and Myocardial Bridge.

We report a case of spontaneous coronary artery dissection located next to a myocardial bridge in a patient with concomitant takotsubo cardiomyopathy. A fusion image with multidetector-row computed tomography and single-photon emission computed tomography played an important role in the diagnosis of these lesions. ().
