Does the type of aortic valve prosthesis affect the amount of backflow in an in vitro pulse duplicating system?
In an in vitro model, the Hancock porcine valve demonstrated significantly less backflow compared to mechanical valves, suggesting potential benefits in low cardiac output states.
Sabbah et al. (1984) studied this question.
