CTICasesAmplatzer Amulet Left Atrial Appendage Occlusion Device
Imaging findings
Fluoroscopic-type images show deployment of a left atrial appendage exclusion device, a newer device distinct from the previously seen Watchman, appearing as a low-opacity structure that is difficult to visualize on plain radiographs but can be seen opening during deployment.
Key takeaways
This is an example of a different manufacturer's percutaneous left atrial appendage occlusion device, and recognizing that multiple such devices now exist beyond the well-known Watchman device is important since they can be subtle on radiographs due to their relatively low radiopacity.
