Management of Inflammatory Cardiac Masses

Abstract

Systemic rheumatologic and inflammatory disorders can affect almost any organ system, including the heart. The cardiac valves, conduction system, myocardium, endocardium, pericardium, and coronary arteries may be affected. Intracardiac masses may develop as part of the disease process or a consequence of their therapy, such as methotrexate-associated nodulosis. Optimal therapy in these cases is not known, since many patients are asymptomatic and the potential benefit of surgical excision must be weighed against its associated morbidity and mortality. Importantly, these inflammatory masses must be differentiated from thrombus, infection, and primary and metastatic tumors. We present three cases of inflammatory cardiac masses associated with rheumatoid arthritis and Wegener's granulomatosis, which were successfully treated conservatively, and propose a management algorithm. The benefits of such an approach must be individualized and weighed against the risks of systemic embolization, stroke and obstruction.
