May standardize in vitro leakage assessment for mechanical valves; leaves open correlation with clinical outcomes or durability.
A quasi-stationary method using a U tube apparatus provides a standardized way to measure and calculate dimensionless loss numbers for leakage in mechanical heart valves.
Wendt et al. (1991) studied this question.
