The previously noted LA mass measured 2.1 cm by 1.4 cm, appeared pedunculated and was attached to the left side of the interatrial septum with echogenic characteristics concerning for atrial myxoma (Figure 1).

Within the right atrium (RA) was a large (3.2 x 2.0 cm) semimobile mural thrombus (Figure 2), and spontaneous echo contrast was also evident in the LV cavity.

Despite this, subsequent TTE imaging demonstrated the development of biventricular thrombi over the course of several days (Figure 3).
