Right Atrial Sarcoma Masquerading As Myxoma Presenting With Fatal Cardiac Tamponade: A Rare Case Report

Primary sarcoma of the heart is an exceptionally rare condition with grave prognosis. All cardiac tumours can cause life threatening complications. Diagnosis is much more challenging as cases present with non-specific symptoms. In our case, a series of investigations were made which ultimately led to our diagnosis of a right atrial sarcoma. Here, we recount a fatal case of a locally invasive primary cardiac sarcoma originating from the right atrium and presenting with a cardiac tamponade.
