Lahoud R, Butzel DW, Parsee A, et al. - By analyzing patients with chronic kidney disease and severe aortic stenosis undergoing surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR) procedure between 2007-2017, researchers examined the incidence as well as predictors of acute kidney recovery (AKR) between SAVR and TAVR. Cases with age < 65 or > 90, dialysis, endocarditis, non-aortic valve stenosis, or patients died within 48-hours post-procedure were removed from this study. A rise of estimated glomerular filtration rate (eGFR) > 25% and a reduction in eGFR > 25% at discharge defined AKR and acute kidney injury (AKI), respectively. They noted AKR in 26% TAVR compared with 23.2% SAVR. Ejection fraction < 50%, female gender, and obesity were identified as independent predictors of AKR. Improved secondary clinical outcomes were reported in relation to AKR vs AKI. Overall, AKR was acknowledged as a generalizable phenomenon, with a frequent and similar occurrence noted in transcatheter or surgical aortic valve patients. Diabetes was identified as a negative predictor of AKR, probably suggestive of less reversible kidney disease.
