Background: Acute kidney injury (AKI) following transcatheter aortic valve implantation (TAVI) is a serious complication and associated with adverse outcomes. In recent study, postoperative AKI is detected in 3.4∼57% in patients undergoing TAVI. However, the diagnostic criteria varied, and many of them used only changes in serum creatinine. The Valve Academic Research Consortium (VARC)-2 criteria was updated and was based on both serum creatinine and urine output. We identify the incidence of AKI after TAVI using VARC-2 criteria.
Method and results: We included 66 patients received either transfemoral (TF, n=49) or transapical (TA, n=17) between February 2014 to September 2015. Overall incidence of AKI was 25.8% (17/66) using VARC-2 criteria. The incidence of AKI was more frequently in TA (64.7%) than TF (12.2%). Multivariate analysis showed a significant impact of TA on AKI (HR: 8.18, P=0.004).
Conclusion: According to the VARK-2 criteria, AKI was developed in 25.8% after TAVI. TA approach was strongly associated to AKI.
