PO-03-193 SINGLE CENTER EXPERIENCE OF TRANSITIONING FROM TRANSESOPHAGEAL TO INTRACARDIAC ECHOCARDIOGRAPHY FOR LEFT ATRIAL APPENDAGE CLOSURE

Left atrial appendage closure (LAAC) is typically performed under peri-procedural transesophageal (TEE) guidance with general anesthesia. LAA guided by intracardiac echo (ICE) imaging in the LA emerging, can provide excellent and allows implant to be done moderate sedation/monitored anesthesia, but requires a learning curve. To compare outcomes of LAAC TEE only vs transition phase using both ICE only. Consecutive patients undergoing Watchman FLXTM implantation from August 2020 November 2022 were included study. The patient population was divided three groups based on utilization (group 1), + 2) (Group 3). Group 2 represent transitioning where institution adapted as standard care while used for confirmation curve operator. Outcomes success, procedural times, adverse events, discontinuation OAC at 45 days assessed. Mean age cohort 74 +/- 8 54 % males. Average CHA2DS2VASc score 4.02 1.2. (TEE+ICE) 90 days. A total 155 underwent FLX [group 1=62, group 2=15 3= 78]. Procedural success achieved 93.5%, 94.7% 97.2% 1, 3 respectively. Procedure times comparable group. There no differences average devices per implant. No major events noted. At there difference incidence PDL. [Table] offers without requiring
