A right atrial mass in the presence of a permanent pacemaker electrode in a patient with polycythemia vera.
A case of a huge right atrial mass that developed 2 years after a permanent pacemaker implantation is described. The patient had a history of polycythemia vera, which is known to present a high tendency towards the development of thrombosis. In light of this fact, we suggest that in similar cases a full echocardiography follow-up should be performed, and long-term anticoagulant therapy should be considered in selected cases.
