Spontaneous Round-Shaped Left Atrial Hematoma

Abstract

Spontaneously occurring left atrial hematomas are very rare and most of them followed acute clinical course due to hemodynamic deterioration. We presented a case of gradually developing hematoma protruding into the left atrial cavity as a round mass, which was completely encapsulated with intact endocardial wall. Emergency surgery was successfully performed. Histopathological study demonstrated subendocardial-aged hematoma with papillary endothelial hyperplasia.
