Medical management of connector pin thrombosis with the Amplatzer cardiac plug left atrial closure device

Figure 1 Forty-five day control. Transesophageal echocardiography two-dimensional X-plane processing, simultaneous visualization at 70° (left) and 13° (right). Successful Amplatzer™ cardiac plug implantation: completely covering the left atrial appendage ostium by the occluder disk and no evidence of device thrombosis.

Figure 2 Four month control. Transesophageal echocardiography two-dimensional image. Adequate covering of the left atrial appendage ostium but little thrombus (7 mm × 7 mm) is observed at the top of the button of the Amplatzer™ cardiac plug.

Figure 3 Transesophageal echocardiography two-dimensional image. A: Control after 2 wk of intravenous sodium heparin treatment. Complete resolution of button thrombosis and correct device positioning; B: 6 mo control. Correct device positioning and absence of button thrombosis.
