Figure 3

67-year-old male after percutaneous transcatheter LAA occlusion using a Watchman device. Figures 3A-D show the temporal sequence of first-pass contrast-enhanced perfusion imaging (see also movie 1 and 2). A (left): contrast-enhancement of the pulmonary trunk (arrow) but not in the left atrium (dotted arrow); typical signal loss at the framework of the device (circle). B (middle): contrast-enhancement in left atrium (dotted arrow) but not inside the device or at the apex of left atrial appendage (circle). C (right): contrast-enhancement of the LAA apex beyond the device representing a slow wash-in due to a small residual leak.
