Brain magnetic resonance imaging showed embolic appearing cortical stroke confined in the posterior superior right middle cerebral artery territory (Figure 1).
Transesophageal echocardiogram shows left atrium (yellow arrow), left atrial appendage (red arrow), intact WATCHMAN device (white line), and peri-device leak (green arrow).

TEE showed an intact WATCHMAN device with 1.8-mm PDL, minimal PFO, and no thrombus (Figure 2). There was no blood flow stasis, no left ventricular dyskinesia, and ejection fraction was 60%.
