Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="jocs12235-sec-0001" sec-type="section"> <p>The Medtronic freestyle aortic root bioprosthesis (Medtronic, Inc., Minneapolis, MN, USA) is a stentless valve with an effective orifice area that is larger than that observed on other bioprostheses. However, there have been sporadic reports of structural valve deterioration (SVD), such as aortic root wall rupture, leaflet tearing, and pseudoaneurysm formation. We report five cases of SVD of freestyle aortic root bioprostheses. doi: 10.1111/jocs.12235 <italic>(J Card Surg 2014;29:22‐25)</italic></p> </sec> </abstract>
