J Am Coll Cardiol Intv 2013;6:479&ndash;86. Acute kidney injury (AKI) presents in 10 to 30% of patients undergoing TAVI; it is associated to the increase of morbidity and mortality and it prolongues hospitalization. This study included 415 patients with<a href="https://solaci.org/en/2013/06/05/what-is-the-contrast-media-dosing-that-predicts-acute-kidney-injury-after-tavi/" title="Read more" >...</a>
