  • Editorial: Less is more: Striving to abolish acute kidney injury in TAVI

    Despite breakthroughs in transcatheter valve implantation (TAVI) over the last decade, acute kidney injury (AKI) remains commonplace, disproportionately afflicting those with advanced chronic kidney disease (CKD) contributing significantly to mortality in these patients [  ]. There are numerous etiologies for AKI following TAVI however, the principal modifiable contributor is contrast media administration, both during TAVI workup and during the TAVR procedure [  ]. Obtaining precise information regarding the size and configuration of the aortic annulus, the coronary ostia and the iliofemoral anatomy is of paramount importance when planning TAVI [  ]. Unfortunately, the cornerstone of pre-TAVI workup is multidetector computed tomography (MDCT) which utilizes a significant amount of contrast in order to provide detailed and accurate information necessary to determine eligibility and guide TAVI [  ]. There are ongoing efforts to design effective strategies to mitigate the amount of contrast administration leveraging the use of multimodality imaging while simultaneously accomplishing successful TAVI [  ].
