Primary undifferentiated pleomorphic sarcoma of the left atrium that presented as acute pulmonary edema.

A 37-year-old woman was admitted to Dong-A University Hospital for rapidly progressive congestive heart failure. Transthoracic echocardiography demonstrated a large mass with a stalk that appeared to be a myxoma on the posterior wall of the left atrium. However, the histological diagnosis was undifferentiated pleomorphic sarcoma. We report a case of primary undifferentiated pleomorphic sarcoma of the left atrium with acute pulmonary edema caused by mitral inflow obstruction.

A case of aortic dissection with fistula from aorta to right ventricle.

Aorto-right ventricular fistula is a very rare complication of aortic dissection. We report a case of acute aortic dissection extending into the right ventricle as documented by echocardiography. The patient survived after successful surgical repair.
