After a second complete release of the occluder and withdrawal of the delivery sheath, the bedside TTE revealed a slightly hyperechoic mass (approximately 6.5 x 3 mm in size) attached to the edge of the left atrial disc of the deployed occluder, oscillating with the movement of cardiac cycle (Figure 1).
Thrombus disappeared over 90% 24 h after tirofiban and heparin infusion (white arrow).

After 24 h, TTE showed that the thrombus had disappeared, and the absorption rate was over 90% (Figure 2).
Transthoracic echocardiography at 1-month post-procedure showed that the thrombus was completely absorbed.

One month later, TTE showed that the occluder was in a good position, and the thrombus on the left disc of the occluder was completely dissolved (Figure 3).
