Acute Kidney Injury Following Transcatheter Aortic Valve Implantation

Abstract

Acute kidney injury (AKI) following transcatheter aortic valve implantation (TAVI) is a serious complication and associated with adverse outcomes. In Recent studies, postoperative AKI is detected in 5.6% - 37.5% in patients undergoing TAVI. However, the diagnostic criteria varied, and many of them used only changes in serum creatinine. The Valve Academic Reserch Consortium (VARC)-2 criteria was updated and was based on both serum creatinine and urine output.We identify the incidence of AKI after TAVI using VARC-2 criteria. Fourty six patients, mean age of 87.1 years, underwent TAVI between February 2014 and March 2015. According to the VARC-2 criteria, AKI developed in twelve (26.1%) of the patients after TAVI. According to the changes in serum creatinine, five (10.9%). At 30 days, 2 patients (4.3%) died. We aimed to show the details of the clinical feature and identify the risk factors for AKI after TAVI using the literature review.
