A simplified acute kidney injury predictor following transcatheter aortic valve implantation: the ACEF score.

BACKGROUND Transcatheter aortic valve implantation ( is an effective, less invasive treatment alternative for symptomatic severe aortic stenosis ( Acute kidney injury ( following TAVI is a common complication and is associated with worse outcomes. ACEF age, creatinine, ejection fraction) score is a simple scoring method, including only three parameters; a ge, creatinine, and ejection fraction ( The score was well established in predicting AKI after coronary interventions. AIMS We aimed to evaluate whether this simple scoring method, ACEF, may predict a development of AKI in patients who underwent TAVI. METHODS A total o f 173 consecutive patients with symptomatic severe AS who underwent TAVI were included retrospectively. The p rimary endpoint of the study was the development of AKI. Study population was divided into two groups according to the presence of AKI. ACEF score was calculated by the formula of age EF + 1 (if baseline creatinine > 2 mg/dL). RESULTS 29 patients developed AKI. The median (Q1 - Q3) ACEF score was 1.36 (1.20 - 1.58). ACEF score was found to be an independent predictor of AKI P < 0.001). ACEF score ≥1.36 predicted AKI development with a sensitivity of 96.6%, specificity of 58.8%. Moreover, hypertension, hemoglobin levels, contrast volume, and aortic valve area ( were found to be independent predictors of AKI. CONCLUSIONS Our study revealed tha t the ACEF score was an independent predictor of AKI. A simple and objective score might be very useful in predicting AKI development in patients undergoing TAVI.
