Contrast‐induced nephropathy in patients undergoing staged vs concomitant transcatheter aortic valve implantation and coronary procedures
Journal of the American Heart Association Jul 30, 2021
Venturi G, Pighi M, Lunardi M, et al. - This inquiry was conducted among patients with aortic stenosis receiving transcatheter aortic valve implantation (TAVI) in order to determine the effect of staged vs concomitant coronary procedures on renal function in this population. A retrospective analysis was performed of 339 patients receiving coronary procedures and TAVI as a staged strategy (160, 47.2%) or concomitant strategy (179, 52.8%). The occurrence of contrast‐induced acute kidney injury (CI‐AKI) was evident in 49 patients in the staged strategy group (30.6%) and in 18 patients (10.1%) in the concomitant strategy group. Findings revealed that a higher risk of CI‐AKI was observed in relation to performing coronary procedures with a staged strategy before TAVI, vs a concomitant strategy. Furthermore, no increase in risk of procedure‐related complications was noted with a concomitant strategy.
