AIMS: The aim of this study was to assess the influence of chronic kidney disease (CKD) classification on clinical outcomes in patients undergoing transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS: Data of 2,929 consecutive patients undergoing TAVI in the FRANCE 2 registry were analysed. Patients were divided into five groups: CKD 1+2, 3a, 3b, 4, and 5. Both 30-day and one-year mortality rates were significantly increased and positively correlated with CKD severity in all groups. After adjusting for significant influential confounders in a Cox regression multivariate model, CKD 4 and 5 were associated with increased risk of both 30-day mortality and one-year mortality when compared with CKD 1+2 as the reference. This higher mortality was predominantly driven by renal failure and infection in patients with CKD 4 and 5, respectively. Procedural success rate in CKD 5 was significantly lower than that in other groups. All CKD patients trended towards a higher incidence of acute kidney injury (AKI), in parallel with the degree of CKD severity. CONCLUSIONS: Classification of CKD stages before TAVI allows risk stratification for 30-day and one-year clinical outcomes. CKD 3b, 4 and 5 correlate with poor outcome and are considered a significant risk for TAVI.
