Abstract

The concept of regional contribution to global ejection fraction (CREF), as a parameter of left ventricular pump function, is introduced. This variable can be derived from regional displacement data and will express quantitatively the relative contribution of a particular left ventricular wall segment to global ejection fraction. Displacement data are assessed with a new model of left ventricular wall motion, based on endocardial landmark trajectories in normal subjects. In order to validate the applicability of this model in patients with asynergy, displacement data and the derived parameter CREF were measured in two groups of patients with heart disease. A strong correlation between the sum of CREF data and global ejection fraction demonstrates that the basic displacement data are accurate.
