Comparison of Two Generations of Self-Expandable Transcatheter Heart Valves in Nine Surgical Valves: An In Vitro Study.

ABSTRACT: (1) Background: This study aimed to analyse the hydrodynamic performance of two generations of self-expanding transcatheter heart valves (THV) as a valve-in-valve (ViV) in different surgical aortic valve (SAV) models under standardised conditions. The nitinol-based Evolut R valve is frequently used in ViV procedures. It is unclear whether its successor, the Evolut PRO, is superior in ViV procedures, particularly considering the previously implanted SAV model. (2) Methods: Evolut^TM R 26 mm and Evolut^TM PRO 26 mm prostheses were implanted in nine 21 mm labelled size SAV models (Hancock^® II, Mosaic^® Ultra^TM, Epic^TM Supra, Trifecta^TM GT, Perimount^®, Perimount^® Magna Ease, Avalus^TM, Int
