Right atrial embolus. Echocardiographic features.

Abstract
Although the value of echocardiography in detecting left heart thrombus is well recognised, right atrial thromboembolism has rarely been identified in life. In 2 patients with pulmonary embolism of varying severity cross sectional echocardiography identified a thrombus moving freely within the right atrium and clearly showed its string-like or even tubular structure. An embolectomy, based on the echocardiographic diagnosis, was undertaken successfully in 1 patient. The value of routine echocardiography in patients with suspected pulmonary embolism is yet to be confirmed.
