Key result
In vitro testing of prosthetic heart valves showed that flow curves of different valve types differ clearly, and combining mean values with time-domain waveforms better reflects pulsatile characteristics.

May refine in vitro prosthetic valve testing; leaves open translation to clinical outcomes or practice change.
Advanced waveform analysis using numerical filtering and constellation graphical methods improves the in vitro evaluation and classification of prosthetic heart valves.
She et al. (1990) studied Prosthetic heart valves (in vitro testing). In vitro testing of prosthetic heart valves was evaluated on Waveform comparison and average value disposition for pulsatile flow. In vitro testing of prosthetic heart valves showed that flow curves of different valve types differ clearly, and combining mean values with time-domain waveforms better reflects pulsatile characteristics.
