Suggests caution with proximal flow convergence at high flows; leaves open need for clinical validation of method refinements.
Does the proximal flow convergence method accurately quantify flow through regurgitant valves in an in-vitro model?
The proximal flow convergence method accurately estimates regurgitant flow at low flow rates, but overestimates flow at higher rates or with large confinement, and angle correction for conical orifices is ineffective at higher flows.
Guenet et al. (1997) studied Valvular regurgitation. Proximal flow convergence method vs. True flow was evaluated on Flow quantification accuracy. Quantification of regurgitant flow using proximal flow convergence accurately estimated true flow at low rates, but overestimated flow at higher rates or large confinement.
