The most important measurement performed by TTE is LVEF, which permits to distinguish patients with cardiac systolic dysfunction from patients with preserved systolic function. LVEF is given by the normalized (non-dimensional) difference between left ventricle End-Diastolic Volume (EDV) and the End-Systolic volume (ESV). Among different models for the computation of such volumes, the American Society of Echocardiography [8] suggests the use of the so-called Simpson’s rule, by which the left ventricle is approximated by a stack of circular (or elliptical) disks whose centers lie in the major axis.
