Gellis L, et al. - Given that contrast-induced acute kidney injury (CI-AKI) after cardiac catheterization is more likely to be seen among adults with congenital heart disease (ACHD), researchers investigated factors that conferred risk for clinically significant CI-AKI and if contrast volume to estimated glomerular filtration rate ratio (V/eGFR) could predict risk of CI-AKI following catheterization in patients with ACHD. They performed a retrospective analysis of ACHD patients who underwent catheterization at Boston Children's hospital between January 2011 and January 2017. According to findings, clinically significant CI-AKI in ACHD patients undergoing cardiac catheterization was strongly predicted by a higher V/eGFR ratio. A poor prognosis was indicated by the development of CI-AKI. Furthermore, development of CI-AKI was found to be related to decreased survival in this population.
