Cardiovascular involvement occurs in 30% to 50% of patients with rheumatoid arthritis and typically presents as nonspecific inflammation or fibrosis of cardiac structures or as nodules embedded in the various cardiac tissues. This case report describes a unique pedunculated, mobile left atrial rheumatoid nodule prolapsing through the mitral valve plane and mimicking an atrial myxoma. A brief discussion of intracardiac rheumatoid nodules and their potential significance follows.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009232	Myxoma	A benign neoplasm derived from connective tissue, consisting chiefly of polyhedral and stellate cells that are loosely embedded in a soft mucoid matrix, thereby resembling primitive mesenchymal tissue. It occurs frequently intramuscularly where it may be mistaken for a sarcoma. It appears also in the jaws and the skin. (From Stedman, 25th ed)	Angiomyxoma,Angiomyxomas,Myxomas
D003937	Diagnosis, Differential	Determination of which one of two or more diseases or conditions a patient is suffering from by systematically comparing and contrasting results of diagnostic measures.	Diagnoses, Differential,Differential Diagnoses,Differential Diagnosis

D006338	Heart Neoplasms	Tumors in any part of the heart. They include primary cardiac tumors and metastatic tumors to the heart. Their interference with normal cardiac functions can cause a wide variety of symptoms including HEART FAILURE; CARDIAC ARRHYTHMIAS; or EMBOLISM.

D012218	Rheumatoid Nodule	Subcutaneous nodules seen in 20-30% of rheumatoid arthritis patients. They may arise anywhere on the body, but are most frequently found over the bony prominences. The nodules are characterized histologically by dense areas of fibrinoid necrosis with basophilic streaks and granules, surrounded by a palisade of cells, mainly fibroblasts and histiocytes.
