PO-01-022 UTILIZATION OF INTRACARDIAC ECHOCARDIOGRAM DURING LEFT ATRIAL APPENDAGE OCCLUSION: EVALUATION OF CARE UTILIZATION

Left Atrial Appendage Occlusion (LAAO) has emerged as a safe alternative for patients with nonvalvular atrial fibrillation at risk bleeding. Transesophageal echocardiography (TEE) been the gold-standard in guiding implantation and pre- post-operative assessment of device location, compression, stability. The intracardiac echocardiogram (ICE) catheter can also be used to provide imaging guidance during transseptal access deployment LAAO, thus providing an TEE general anesthesia (GA). To review requirements, procedural efficiency, hospital length stay who underwent ICE guided (IG) vs TEE-guided (TG) LAAO. This is retrospective observational study including LAAO between Nov 2020 2022 single center, 4 operators. Variables analyzed included guidance, success, stay, clinical outcomes. Chi squared multivariate t-test were evaluate differences groups. Of total 120 that this period, 64 performed IG 56 TG. Baseline characteristics similar groups (Table 1). Among those had IG, 47(73%) monitored (MAC) 17(27%) GA compared 2(4%) MAC 54(96%) TG group (P<0.0001). Total time EP lab fluoroscopy Acute success was similar, 98% group, 96% (P= 0.9471). Same day discharge successful 22(34%) 17(30%) 0.639). There no statistically significant difference peri-device leak among two follow up regardless type modality (Figure Our results revealed outcomes TE Therefore, highlights periprocedural long-term equivalent Utilizing significantly reduces anesthetic requirements while maintaining safety, success. Consequently, implementation could increase volume capacity electrophysiology labs are currently limited due anesthesiologist availability.Tabled 1Table 1VariableIce-GuidedTEE-GuidedP-valueAge76.475.90.7539CHADS2Vasc4.44.20.5551LVEF58530.0763Pre-procedure CT scan6242<0.0001Monitored Anesthesia472<0.0001General Anesthesia1754<0.0001Acute success63520.9471Total (minutes)1301280.86Total (minutes)1413.80.8796 Open table new tab
