Implication
May support volume replacement for post-valve low-output states; leaves open applicability in contemporary cohorts with residual disease.

Outcome
Cardiac output and blood volumesurrogate
Cardiac valve replacement leads to a prompt increase in cardiac output, and postoperative low cardiac output associated with reduced blood volume responds well to volume replacement unless residual valvular or myocardial disease is present.
