Performance Analysis of the Transcatheter Aortic Valve Implantation (TAVI) on Blood Flow Hemodynamics: An Optical Imaging‐based In Vitro Study

...In this study, we aimed at investigating the impact of transcatheter aortic valve implantation (TAVI) devices on blood flow patterns that develop in the ascending aorta under physiological flow conditions in vitro... … Graphics, Heidelberg, Germany). Valve hydrodynamics A Pulse Duplicator System (ViVitro Labs Inc) was used for the assessment of heart valve performance and function under simulated cardiac conditions. The system is a … ...We conclude that the characteristics and material designs of TAVI devices have strong influences on the hemodynamics in the ascending aorta...
