Right atrial myxoma with extracardiac manifestations.

Right atrial myxoma is a rare intracardiac tumor that is often difficult to diagnose. Pulmonary embolism from tumor fragments originating from the tumor mass is a potentially fatal complication. Early diagnosis of cardiac myxoma is important since surgical treatment leads to resolution with low rates of recurrence and good long-term survival. The presence of a cardiac myxoma can be heralded by nonspecific constitutional symptoms as well as by disturbances in the clotting mechanism.
