ABSTRACT
Two-dimensional echocardiography permitted identification of a large free-floating left atrial thrombus in a patient with mitral stenosis. A specific pattern of motion afforded its recognition and differentiation from mural left atrial thrombosis and tumors. Phonocardiographic tracings revealed a non-ejection systolic click and opening snap. A gated blood pool scintigram disclosed a left atrial filling defect. Subsequent left atrial angiography and left atriotomy confirmed the non-invasive findings.

A 44-year-old woman with a superior caval syndrome was found to have an isolated plasmacytoma of the right atrium causing partial obstruction of the superior and inferior vena cavae. The tumor was excised locally, and after operation, irradiation was given. There has been no local recurrence or systemic disease demonstrated after 30 months. This is the first reported surgical excision of an intracardiac plasmacytoma.
