Case Reports Right Atrial Trombus Over Eustachian Valve: A Case Report

Patients with pulmonary thromboembolism have occasionally been seen to have thrombi in the right atrium, either free floating or attached by a narrow pedicle. These thrombi may occur without any demonstrable cause or accompany various infiltrative inferior vena caval disease. However, thrombi attached to the Eustachian valve is extremely rare. In this case we describe a patient, in whom a right atrial mass was long, narrow, rounded and had a spiral shape; while the bottom was attached over the Eustachian valve, the tip moved freely into the right ventricle. The diagnosis of thrombus was established only after the removal of the mass surgically. To our konwledge, similar description in the literature is lacking.
