Thromboembolism Prevention via Transcatheter Left Atrial Appendage Closure with Transeosophageal Echocardiography Guidance

Figure 2

TEE images at mid-esophageal 92 degrees suggestive of a thrombus in LAA in a patient planning for LAA closure. In 2D image (a) a clot is seen in the LAA (white arrow). In pulsed wave Doppler image (b) the LAA wash-out velocity is low (<0.4 m/s). The LAA occlusion procedure was cancelled.
