Abstract

Objectives: To assess the relation of sphericity index to left ventricular (LV) twist in patients with ischemic cardiomyopathy (ICM) using speckle tracking imaging. Background: ICM is the presence of significant LV systolic dysfunction (ejection fraction (EF) ≤ 40%)  secondary to coronary artery disease (CAD). LV twist has an important role in determining LV-EF. This twisting deformation depends on the angle between the epicardial and endocardial myofibers which is related to LV sphericity index.
