Background Acute kidney injury (AKI) is a serious complication after invasive cardiac procedures and has been associated with a higher incidence of periprocedural complications and increased mortality. Data on the occurrence of AKI associated with left atrial appendage occlusion (LAAO) are very limited. Purpose To report the incidence, predictors, and clinical implications of AKI following percutaneous LAAO. Methods This multicenter registry included 2124 patients with successful Watchman implantation. AKI was defined according to the AKI Network criteria as an increase in serum creatinine of ≥0.3 mg/dL or of ≥50% over the course of 48 hours post-procedure. Patients meeting this definition were further categorized in three stages: stage 1, increase in serum creatinine ≥ 0.3 mg/dl (≥ 26.4 μmol/l) or of 1.5 to 2 times compared to baseline; stage 2, increase in serum creatinine of 2 to 3 times compared to baseline; stage 3, increase in serum creatinine of > 3 times compared to baseline or serum creatinine ≥ 4.0 mg/dl [≥ 354 μmol/l] with an acute increase of at least 0.5 mg/dl [44 μmol/l]. Results Post-procedural AKI was documented in 68 (5.5%) of 1234 patients with creatinine determination between 24 and 48 hours post-LAAO. Among them, 63 (92.6%) patients had AKI stage 1, 4 (5.9%) had AKI stage 2, and 1 (1.5%) had AKI stage 3. AKI was associated with higher CHA2DS2-VASc (5.3 ± 1.4 vs. 4.8 ± 1.4; p=0.001) and HAS-BLED (3.8 ± 0.9 vs. 3.5 ± 1.0; p=0.01) scores at baseline, as well as a higher prevalence of diabetes mellitus (p=0.04) and CHF (p At multivariate analysis (Table 1), independent predictors of AKI were CKD stage 4/5 (OR: 1.998; 95% CI: 1.018 – 3.923; p=0.04), and CHF (OR: 2.286; 95% CI: 1.328 – 3.934; p=0.01). The average follow-up was 13 ± 7 months. The annualized rates of cardiovascular mortality were 5.5% in AKI and 1.0% in non-AKI patients (p=0.01). The annualized rates of overall mortality were 15.1% in AKI and 3.4% in non-AKI patients (p Conclusion AKI was an infrequent complication following percutaneous LAAO and a powerful predictor of cardiovascular and overall mortality during follow-up.
