OBJECTIVES: The aim of this study was to determine the influence of baseline renal function and periprocedural acute kidney injury (AKI) on prognosis after transcatheter aortic valve implantation (TAVI). BACKGROUND: Evidence is growing that renal function is a major predictor of mortality in patients after TAVI. METHODS: TAVI was performed with the 18-F CoreValve prosthesis via transfemoral access. All-cause mortality was determined 30 days and 1 year after TAVI in 77 patients with a mean Society of Thoracic Surgeons mortality score of 9.3 ± 6.1% and a mean logistic European System for Cardiac Operative Risk Evaluation of 31.2 ± 17.6%. RESULTS: Overall procedural success rate was 98% with 1 periprocedural death. The 30-day mortality was 10%, and 1-year mortality was 26%. The mortality risk increased stepwise across quartiles of baseline serum creatinine. An AKI occurred in 20 of 77 patients: 12 patients (60%) with AKI died during follow-up. The incidence of AKI was related to peripheral arterial disease (65% vs. 39%; p = 0.04), the occurrence of a systemic inflammatory response syndrome (60% vs. 21%, p = 0.002), and post-procedural peri-prosthetic regurgitation ≥2+ (35% vs. 9%, p = 0.02). Impaired renal function at baseline reflected by serum creatinine ≥1.58 mg/dl (hazard ratio: 3.9, 95% confidence interval: 1.6 to 9.5; p = 0.002) and the occurrence of AKI (hazard ratio: 5.9, 95% confidence interval: 2.4 to 14.5, p < 0.001) that was not related to the amount of contrast dye were strong predictors of 1-year mortality after TAVI. CONCLUSIONS: Impaired renal function at baseline and the occurrence of periprocedural AKI, independent whether renal function returns to baseline or not, are strong predictors of 30-day and 1-year mortality after TAVI.
