Clinical Case: Direct Diagnosis of Pulmonary Embolism on Echocardiography

Ultrasound diagnosis of pulmonary embolism by direct visualization of a thrombus in the pulmonary artery is exceptional. In this work, we report a case of pulmonary embolism revealed by thrombi in the right atrium and in the common trunk of the pulmonary artery, discovered on echocardiography. A 65-year-old patient admitted with predominantly right heart failure. Echocardiography shows a large, floating right intraauricular thrombus and thrombus in the common trunk of the pulmonary artery. The patient's hemodynamic status was stable. Long-term anticoagulation allowed the thrombi to disappear. It is rare to find a thrombus directly in the pulmonary artery on ultrasound. There is no recommendation for the management of right intracavitary thrombi. Our patient received long-term anticoagulation with K antivitamins.
