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 dis closed a left atrial filling defect. Subsequent left atrial angiography and left atriotomy confirmed the non-invasive findings.
