Measurement and display of regional myocardial motion during post infarct treatment.
Quantitative assessment of 3-D regional heart motion has significant potential to provide more specific diagnosis of cardiac malfunction than currently possible. Using functional parametric mapping, regional myocardial motion during a cardiac cycle can be color-mapped onto a deformable heart model to provide better understanding of the structure-to-function relationships in the myocardium, including regional patterns of akinesis or dyskinesis associated with ischemia or infarction. In this study, 3-D reconstructions of human hearts were obtained from Electron-Beam Computed Tomography [1] (EB-CT), comparing stages of treatment after myocardial infarction.
