The ratio of contrast volume to glomerular filtration rate predicts acute kidney injury and mortality after transcatheter aortic valve implantation

A V/GFR > 3.2 was found to be correlated with a higher incidence of AKI and mortality after TAVI. Therefore, this ratio could potentially be used to calculate the maximum volume of contrast medium that can be administered without significantly increasing the risk of AKI and mortality. Further larger studies are needed to validate these findings.
