Figure 2 CT images showing complete LAA closure by Watchman device (A), peri-device leak (B), and trans fabric leak (C).
Panel A shows no evidence of contrast enhancement within the Watchman device or beyond its edges. Panel B shows peri-device leak (red arrow) with contrast traversing around the device into the distal portions of the LAA. Panel C shows an incomplete device seal with evidence of contrast uptake within the device but not at its proximal border, suggesting residual permeability of the fabric.CT, computed tomography; LAA, left atrial appendage
