BackgroundPercutaneous left atrial appendage closure (LAAC) has been proposed as an alternative to anticoagulation therapy in patients with nonvalvular atrial fibrillation to decrease the thromboembolic risk, while avoiding the risks of chronic anticoagulation. This option may be attractive in patients with nonvalvular atrial fibrillation and chronic kidney disease (CKD), since they exhibit both high-thromboembolic and bleeding risks.ObjectiveTo evaluate the prognostic impact of the presence of CKD in patients with atrial fibrillation undergoing LAAC peri-procedure and during the follow-up as compared with patients with preserved renal function.MethodsRetrospective, observational study that included 124 consecutive patients with atrial fibrillation undergoing LAAC in a university hospital, and the results were evaluated according to the baseline renal function of the patients.ResultsThe median age was 75.5 years (IQR 67.6–80) and 62.1% were men, the median of CHA2DS2-Vasc and HASBLED scores was 4 (IQR 3–4) for both scores. Up to 57.3% of the total sample had CKD. Baseline characteristics were similar between groups, but CKD patients were older and had a higher HASBLED score. During the procedure, no thromboembolic, bleeding events, or deaths were observed. Combining the time of hospitalization and follow-up, no significant differences were observed between groups in the annual rate of thromboembolic events (0.97/100 patient-years [100PY] vs. 4.06/100PY, p = .09), but there was a higher rate of bleeding events (5.67/100PY vs. 13.3/100PY, p = .033) and mortality among CKD patients (6.50/100PY vs. 17.2/100PY, p = .009), with an odds ratio of 2.711 (95% CI 1.96–6.95). In the multivariate analysis, a preserved eGFR was independently associated with a lower mortality risk.ConclusionsLAAC is a valid alternative to oral anticoagulation in patients with CKD and atrial fibrillation, with a low-rate of peri- and post-procedure complications, although CKD patients exhibited a higher risk of bleeding and mortality during the follow-up. However, these higher rates may not be necessarily related to the procedure. 相似文献
