• W4289868983 abstract "Background Data on percutaneous left atrial appendage closure (LAAC) outcomes in the very elderly with atrial fibrillation are limited. We aimed to investigate the clinical characteristics and short-term outcomes of patients 80 years or older following percutaneous LAAC in a large nationwide database. Methods and Results Using the Nationwide Readmissions Database, we identified patients who underwent percutaneous LAAC between January 2016 and December 2018. Patients were categorized based on age (≥80 and <80 years old). The primary outcome was in-hospital mortality. Secondary outcomes were in-hospital end points including periprocedural complications, 30-day outcomes, and all-cause 30-day readmissions. A propensity score-matched model (1:1) was used to adjust for baseline characteristics among the study groups. A total of 13 208 patients were included in this study (43% women, median age in years [interquartile range] 79.5 [73-84]) and matched one-to-one (6604 and 6604 patients were ≥80 and <80 years old, respectively). In-hospital mortality was not statistically different between the study groups and occurred in 21 patients ≥80 years old (0.32%) and in 14 patients <80 years old (0.21%); P=0.236. Rates of in-hospital stroke/transient ischemic attack were higher in patients ≥80 years old compared with those <80 years old (1.22% versus 0.77%; P=0.009). In-hospital bleeding requiring transfusion, vascular complications, systemic embolization, and pericardial effusion/tamponade requiring pericardiocentesis or surgical intervention occurred more frequently in patients ≥80 years old. Furthermore, the elderly group was more likely to be readmitted within 30 days compared with those <80 years old (9.91% versus 8.4%; P=0.004); however, rates of 30-day complications were not statistically different between the study groups. Conclusions In a large nationwide database, patients ≥80 years old undergoing percutaneous LAAC were found to have similar in-hospital mortality but an increased risk of periprocedural complications and 30-day readmission compared with younger patients. Our data suggest that LAAC should be considered on a case-by-case basis in the very elderly, taking into consideration the risks and benefits of this intervention. Further studies are needed to assess long-term LAAC outcomes in this high-risk population." @default.
