Why the study?
Because artificial valves can replace disabled heart valves, a feasible in vitro evaluation system is important prior to implantation.
Does transcatheter heart valve V-A compared to V-B improve fluid dynamics in an in vitro circulation system?
Population
Two types of transcatheter heart valves, V-A (diameter: 23 mm) and V-B (diameter: 25 mm)
Comparison

Informs preclinical transcatheter valve design; leaves open in vivo performance and safety validation.
Does transcatheter heart valve V-A compared to V-B improve fluid dynamics in an in vitro circulation system?
In vitro particle image velocimetry demonstrates that the V-A (23 mm) transcatheter heart valve has superior fluid dynamics compared to the V-B (25 mm) valve.
