抄録

Left atrial thrombus, which is a frequent finding in patients with mitral valve disease, is generally attached to the atrial wall. Left atrial free-floating thrombus has rarely been reported. Since the risk of peripheral emboli is fairly high, patients with such a thrombus are candidates for emergency surgery. Our first case was a 45-year-old female with mitral stenosis and regurgitation. The typically appearing free floating thrombus with a diameter of 3.4cm was detected by two-dimensional and M-mode echocardiography, and an appropriate surgical procedure was performed. The surgical findings were consistent with the echocardiographic findings. Our second case was a 59-year-old female. A free floating thrombus with a diameter of 2cm was detected by echocardiography when this patient with mitral stenosis was hospitalized because of right hemiplegia and aphasia. The thrombus was extracted by an immediate surgical procedure. <br>Transthoracic echocardiographic (TTE) study was definitely specific in both cases; no other study was thus required.
