    BackgroundPatients with chronic kidney disease (CKD) experience atrial fibrillation more frequently. The balance of medical management for stroke prevention and bleeding events presents a challenging issue in CKD population. Left atrial appendage occlusion (LAAO) may be an effective solution for stroke prevention in patients who experience frequent bleeding with oral anticoagulants. However, the specific impact of CKD on the procedural success, complications, and outcomes of LAAO implantations remains underexplored.MethodsWe conducted a search of various databases for articles published before October 31, 2023. This search yielded 7 studies, comparing outcomes between CKD and non-CKD cohorts undergoing LAAO implantation. Our analysis focused on CHA2DS2-VASc scores, average eGFR, use of oral anticoagulants, procedural success rates, procedural complications, and associated outcomes.ResultsThe meta-analysis included data from 2576 patients, with 1131 identified as having CKD. The CKD group also had higher CHA2DS2-VASc scores (4.7 ± 1.4 vs 4.0 ± 1.5; P < .001) and HAS-BLED scores (3.8 ± 1.1 vs 3.1 ± 1.0; P < .001) than the non-CKD group. CKD patients showed a nonreduction in procedural success rates and a nonsignificant increase in total complications. The risks of stroke and transient ischemic attack, major bleeding, and cardiovascular mortality were not significantly different between the 2 groups. However, a significantly lower rate of total mortality was observed in the non-CKD group (odds ratio: 0.43; 95% confidence interval, 0.32-0.60).ConclusionWhile CKD is associated with a nonsignificant decrease in procedural success and a nonsignificant increase in complication risks, the outcomes of LAAO implantation are comparably favorable between CKD and non-CKD groups. Despite similar procedural outcomes, the CKD group exhibited a higher rate of all-cause mortality.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
