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;
