Implication

Caution interpreting in vitro prosthetic valve data; leaves open rigorous standardization of test conditions.

Structured PICO

Population

Seven popular mechanical prostheses (sizes 29 and 27 mm) evaluated in the mitral position

Intervention

Evaluation under five different flow conditions using a servo-controlled pump test rig

Outcome

Mean pressure difference, root mean square (RMS) forward flow and regurgitant volumessurrogate

In vitro testing of prosthetic heart valves requires carefully specified test conditions, as variations in setup can produce differences in measured function comparable to differences between the valves themselves.
