Incidence and predictors of acute kidney injury in patients undergoing transcatheter aortic valve implantation

Incidence, risk factors and prognostic impact of acute kidney injury on 30-day mortality after transcatheter aortic valve implantation

“…[21] Similar to the previous findings, [4][5][6][7][8][9] baseline eGFR and the amount of contrast media used were not associated with AKI in the univariate analysis in our study. The finding that AKI was not related to the amount of the contrast agent used suggests that other factors may be more important for the development of renal impairment in the population undergoing TAVI.…”

“…However, Elhmidi et al, [6] Alassar et al, [14] and Strauch et al [20] found that baseline SCr levels were independent predictors of AKI following TAVI.…”

“…Several studies have investigated the incidence and predictors of AKI after TAVI. [4][5][6][7][8][9][10][11][12][13][14] Previous studies have shown that AKI occurs in about 11.7 to 41.7% of patients undergoing TAVI and has been associated with 2-to 5.47-fold increased risk of mortality. [5][6][7][8][9][10] In the present study, we aimed to determine the incidence, predictors, and prognostic impact of AKI on 30-day mortality following TAVI.…”

92 Transcatheter Aortic Valve Implantation in Patients with Pre-existing Chronic Kidney Disease

“…Our data demonstrates a trend to an increased rate of AKI in the CKD group although this effect was attenuated somewhat when entered into a multivariate model including other notable risk factors from univariate analyses. Elhimidi et al [43] demonstrated pre-procedural serum creatinine level to be a predictor of AKI (OR [95% CI] 3.7 (1.24-11.3); p = 0.019) as did Khawaja et al [44] (OR [95% CI] 1.57 (1.11-2.21); p = 0.010) who also, like our study found pre-existing diabetes to strongly predict AKI. Other series however have not found an association between baseline renal function or the presence of CKD and AKI development after TAVI [29,41,45,46].…”

Minimally invasive aortic valve replacement—where are we?

“…The reduced rates of bleeding with SuAVR were attributed to limited wound bleeding due to the minimally invasive technique used, a mechanism similar to TAVR (20). Lower rates of bleeding have been associated with reduced rates of acute renal failure, which can explain the lower rates of acute renal failure with SuAVR as well (21,22). However, SuAVR suffered from the higher rates of pacemaker implantation rates as seen with TAVR.…”
