Abstract

In the study, proposed is the Energy Index method which presents the user with a single parameter that is physically meaningful and encompasses characteristics of the valve's behavior both during the forward and during the closure and closed stages of the cardiac cycle. The Energy Index is the ratio of the total hydraulic energy delivered across a value, THED, to the energy available upstream of said value. The use of the Energy Index Method requires on-line measurement of the transvalvular flow rate and pressure drop.
