Abstract

The age-based trends in-hospital outcomes in patients with percutaneous left atrial appendage occlusion (LAAO) are unknown. Using the National Readmission Database from 2016 to 2019, patients who underwent LAAO were divided into 2 age groups: 60 to 79 and ≥80 years. The primary objective was to evaluate the age-based trends in the outcomes related to LAAO. The secondary objectives were to evaluate the mean cost and total cumulative cost of readmissions in both age groups in 2019. We identified 58,818 patients who underwent LAAO, of whom 36,964 (63%) were aged 60 to 79 years, and 21,854 (37%) were ≥80 years. The hospital mortality, pericardial complications, acute kidney injury, and in-hospital cardiac arrest did not change over time. The risk-adjusted postoperative stroke and bleeding requiring blood transfusion decreased in patients aged ≥80 years (p trend 0.03 for both outcomes). The length of stay decreased, and early discharge rates increased over time in both the unadjusted and risk-adjusted models in both age groups. The risk-adjusted 90-day readmission rates also decreased in patients aged ≥80 years. The inflation-adjusted cost did not change over time on the unadjusted and adjusted analyses. The total cumulative all-cause 90-readmission cost for both groups in 2019 was $31.7 million. Most outcomes after LAAO either improved or did not change from 2016 to 2019. Hospital mortality has remained
