Key result
In vitro flow visualization demonstrated that mitral tilting disc valves produced a large vortex, while aortic ball valves produced less flow disturbance than tilting disc or porcine bioprostheses.

In vitro valve flow differences warrant no clinical change; leaves open in vivo outcome relevance.
Different prosthetic heart valves produce distinct flow patterns in vitro, with aortic ball valves showing less flow disturbance than tilting disc or bioprosthetic valves.
Wright et al. (1977) studied Prosthetic heart valves. Prosthetic aortic and mitral heart valves vs. Different valve types (tilting disc, ball, bioprosthesis) was evaluated on Flow patterns and flow disturbance. In vitro flow visualization demonstrated that mitral tilting disc valves produced a large vortex, while aortic ball valves produced less flow disturbance than tilting disc or porcine bioprostheses.
