...Bench study assessed the hydrodynamic performance of different sizes of self‐expanding supra‐annular THVs in three different surgical aortic bioprostheses at different implantation depths.... ...A small versus medium ACURATE neo (ACn), and a 26 mm versus 29 mm Evolut R were assessed after VIV implantation in 25 mm Mitroflow, Mosaic, and Magna Ease aortic surgical bioprostheses, at three implantation depths (+2 mm, ‐2 mm, and ‐6 mm).... ...Use of a larger self‐expanding THV was associated with superior hydrodynamic performance if the THV was implanted high....

Objectives This study assessed the effect of overexpansion beyond labeled size (diameter) of transcatheter heart valves through an ex vivo bench study... Background Transcatheter heart valves function optimally when expanded to specific dimensions. However, clinicians may sometimes wish to overexpand balloon-expandable valves to address specific clinical challenges. The implications of overexpansion have assumed considerable importance, and objective information to guide practice is limited...
