Ascites and Other Extracardiac Manifestations Associated with Right Atrial Myxoma

Abstract

Right atrial myxomas are rare intracardiac tumors that often pose difficulties in diagnosis. Right ventricular failure and ascites ensuing from tricuspid valve orifice obstruction are potentially dangerous complications. Early diagnosis of cardiac myxoma is important since surgical treatment leads to disappearance of all symptoms with a low rate of recurrence and good long-term survival. Nonspecific extracardiac symptoms, signs, complications, and laboratory findings may be the initial manifestations contributing to misdiagnosis of these rare but totally treatable atrial tumors.
