Left atrial appendage sealing performance of the Amplatzer Amulet and Watchman FLX device

  Fig. 1. Patient flow chart. *LAAO performed in trials restricted to Watchman 2.5 use. **LAAO closure performed in clinical trials or educational sessions restricted to Amulet device use. Patient enrolment or inclusion in educational sessions were prior to preprocedural CT acquisition and knowledge of the LAA anatomy. LAAO, left atrial appendage occlusion

  Fig. 3. Complete LAA occlusion stratified by device cohorts into implant tertiles. Primary outcome stratified by tertiles of each device implantation cohort to assess for potential operator learning curve. The y-axis shows percent of patients having complete LAA occlusion defined as no visible PDL and absence of distal LAA contrast patency. LAA, left atrial appendage
