Right atrial thrombus over eustachian valve--successful lysis with streptokinase

Patients with pulmonary thromboembolism have occasionally been seen to have thrombi in the right atrium, either free floating or attached by a narrow pedicle. An echocardiographic description of a thrombus attached to the eustachian valve has, however, never been made in the literature. One such case is described in which streptokinase successfully lysed the thrombus.
