Safety and efficacy of left atrial appendage occlusion with the ACP or Watchman device guided by intracardiac echocardiography from the left atrium.

ICE in the left atrium to guide LAAO procedures appears to be as effective and safe as TEE. There was no increase in procedure-related complications, whatever the device used. ICE resulted in similar procedural success while decreasing procedure time and requiring only local anesthesia.
