<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="ccd24951-sec-0001" sec-type="section"> <title>Background</title> <p>The relative radiation dose (RD) of patients undergoing transcatheter aortic valve implantation (TAVI) with either the Edwards Sapien XT (ESX) or the Medtronic CoreValve (MCV) prostheses has not been studied in depth.

Though mean fluoroscopy time was higher during ESX valve implantation, overall RD per total air Kerma and DAP was significantly higher during MCV implantation (<italic>P</italic> < 0.05 for both comparisons). By multivariate regression analyses, prosthesis type was an independent predictor of RD according to both total air Kerma and DAP (<italic>r</italic><sup>2</sup> = 0. 498; <italic>P</italic> < 0.01 and <italic>r</italic><sup>2</sup> = 0.363; <italic>P</italic> < 0.01, respectively).</p> </sec> <sec id="ccd24951-sec-0004" sec-type="section"> <title>Conclusion</title> <p>In uncomplicated transfemoral TAVI, RD is greater during MCV implantation than during ESX implantation. © 2013 Wiley Periodicals, Inc.</p> </sec> </abstract>
