Implication for health policy/practice/research/medical education:
In our recent updated studies, we found a significant association between periprocedural blood transfusion and acute kidney injury (AKI) following transcatheter aortic valve replacement (TAVR) with an overall 1.95-fold increased the risk of AKI. We also demonstrated that a transapical approach was significantly associated with increased AKI risk compared with a transfemoral approach. Nevertheless, the TAVR approach did not affect severe renal outcomes or long-term renal function. In addition, our meta-analysis demonstrated no significant association between contrast media volume and risk of AKI after TAVR. Thus, the dose of contrast media likely does not play a significant role in the pathogenesis of TAVR-related AKI. Growing knowledge of these risk factors of TAVR on kidney function will help improve preventive measures to improve patients’ outcomes.
