The Risk of Acute Kidney Injury and Its Impact on 30-Day and Long-Term Mortality after Transcatheter Aortic Valve Implantation
Background. Transcatheter aortic valve implantation (TAVI) is widely used in high risk patients (pts) with aortic stenosis. Underlying chronic kidney disease implicates a high risk of postprocedural acute kidney injury (AKI).We analyzed its occurrence, impact on hospital stay, and mortality. Methods...

Background. Transcatheter aortic valve implantation (TAVI) is widely used in high risk patients (pts) with aortic stenosis. Underlying chronic kidney disease implicates a high risk of postprocedural acute kidney injury (AKI).We analyzed its occurrence, impact on hospital stay, and mortality. Methods. 150 consecutive pts underwent TAVI in our institution (mean age 81±7 years; logistic EuroSCORE 24±15%). AKI definition was a creatinine rise of 26.5 μmol/L or more within 48 hours postprocedural. Ten patients on chronic hemodialysis were excluded. Results. AKI occurred in 28 pts (20%). Baseline creatinine was higher in AKI pts (126.4±59.2 μmol/L versus 108.7±45.1 μmol/L, P = 0.09). Contrast media use was distributed evenly. Both, 30-day mortality (29% versus 7%, P < 0.0001) and long-term mortality (43% versus 18%, P < 0.0001) were higher; hospital stay was longer in AKI pts (20±12 versus 15±10 days, P = 0.03). Predicted renal failure calculated STS Score was similar (8.0±5.0% [AKI] versus 7.1±4.0% [non-AKI], P = 0.32) and estimated lower renal failure rates than observed. Conclusion. AKI remains a frequent complication with increased mortality in TAVI pts. Careful identification of risk factors and development of more suitable risk scores are essential.
