    Description of Event or Problem · 0

    REPORTED VIA LITERATURE ARTICLE IT WAS REPORTED DEATH(S) OCCURRED. THE NATIONAL CARDIOVASCULAR DATA REGISTRY LEFT ATRIAL APPENDAGE OCCLUSION (LAAO) REGISTRY DATA WAS USED FOR INPATIENT MEDICARE CLAIMS DATA USING DETERMINISTIC MATCHING AND ESTABLISHED A COHORT OF PATIENTS >/=65 YEARS OF AGE WHO UNDERWENT LAAO BETWEEN JANUARY 2016 AND DECEMBER 2019. EVENT FREE SURVIVAL WAS CALCULATED USING THE KAPLAN-MEIER METHOD FOR DEATH AND THE CUMULATIVE INCIDENCE FUNCTION, ACCOUNTING FOR COMPETING RISK OF DEATH, FOR STROKE. RESULTS: A TOTAL OF 34,975 PATIENTS WITH AN AVERAGE AGE 77.5 YEARS (SD 6.5) AND 41.8% FEMALE WERE INCLUDED. THE AVERAGE CHA(2) DS(2)-VASC SCORE WAS 4.7 (SD 1.4). MEDIAN FOLLOW-UP WAS 2.8 YEARS (IQR 2.2-3.7 YEARS). THE INCIDENCE OF ANY STROKE AND ISCHEMIC STROKE WERE 1.80 (95% CI 1.66-94) AND 1.47 (95% CI 1.35-1.59) PER 100 PERSON-YEAR, RESPECTIVELY. THE FIVE-YEAR RATES OF ANY STROKE AND ISCHEMIC STROKE WERE 5.70% (95% CI 5.37-6.05) AND 5.03% (95% CI 4.71-5.36%), RESPECTIVELY. THE INCIDENCE OF DEATH WAS 10.37 (10.05-10.68) PER 100 PERSON-YEARS AND THE FIVE-YEAR MORTALITY RATE WAS 44.34% (95% CI 43.45-45.23%). CONCLUSION: LONG-TERM ISCHEMIC STROKE RATES IN A LARGE NATIONALLY REPRESENTATIVE COHORT OF MEDICARE PATIENTS FOLLOWING WATCHMAN LAAO WERE LOW DESPITE A HIGH EMBOLIC RISK.
