Cardiac sarcoma presenting as heart failure and diagnosed as recurrent myxoma by echocardiogram

Abstract

We report a case of an extremely rare high-grade, undifferentiated cardiac sarcoma. The patient with left atrial myxoma resected 8 months ago presented with pneumonia, congestive heart failure, and subsequently diagnosed to have cardiac sarcoma. Transoesophageal echocardiogram played an important role in diagnosis of left atrial mass. High index of suspicion is required to diagnose left atrial tumour as initially it can present as pneumonia or congestive heart failure and left atrial tumours are not always the myxoma.
