Abstract
BACKGROUND: The use of transcatheter edge-to-edge repair (TEER) for symptomatic mitral regurgitation is steadily increasing. However, the outcomes of TEER among patients with atrial fibrillation (AF), including readmission trends, remain unknown.
METHODS: The Nationwide Readmissions Database was queried between 2016 to 2020 to identify TEER patients with and without AF. The two groups were then compared using propensity score matching (PSM) and multivariate regression models. The outcomes included in-hospital mortality, acute kidney injury (AKI), heart failure, acute stroke, myocardial infarction (MI), post-procedure bleeding (PPB), and cardiac tamponade.
RESULTS: A total of 39,867 TEER procedure recipients were included over the study period, of which, 24,729 (62%) had AF compared to 15,138 (38%) with no AF diagnosis. On adjusted analysis, the AF group had a higher rate of inpatient mortality, AKI, heart failure (HF), and post-procedural bleeding (PPB). On the contrary, TEER with AF group had lower odds of MI. The risk of stroke and cardiac tamponade were similar between the two groups. The median length of stay (LOS) at index hospitalization was longer in the AF cohort in comparison with those without (2 days (IQR 5-1) vs 1 day (IQR 3-1)).
CONCLUSION: AF in TEER procedure recipients was associated with worse outcomes including a higher rate of inpatient mortality, AKI, and HF compared to the patients without AF. Readmission rates at 30, 90, and 180 days were similar between the two groups.
