Does cardiac computed tomography differentiate device-related thrombus from benign device healing following Watchman FLX implantation?
Specific CT findings such as pedunculated or protruding hypoattenuation thickening can help identify true device-related thrombus versus benign healing after Watchman FLX implantation.
Subfabric hypoattenuation and flat sessile HAT are frequent CT findings for Watchman FLX, likely representing benign device healing and endothelialization. Pedunculated HAT and protruding HAT are infrequent CT findings that might represent DRT.
