title: [Echocardiographic assessment of left ventricular myocardial deformation by automatic functional image in patients with sigmoid interventricular septum].
abstract: OBJECTIVE
  To assess a new method of automatic functional image for estimation of maximal systolic longitudinal strain of left ventricular (L) myocardium in patients with sigmoid interventricular septum (IVS) with normal LV ejection fraction.
  
  
  METHODS
  Maximal systolic longitudinal strain was compared in patients with sigmoid IVS (SIVS) and in 21 patients of the control group.
  
  
  RESULTS
  Compared to controls, patients with SIVS have significantly greater global longitudinal systolic LV strain in two septal segments in the region of sigmoid-shape IVS.
  
  
  CONCLUSIONS
  Local aggravation of maximal systolic longitudinal LV myocardium strain in SIVS zone can be one of the causes of dynamic obstruction of the efferent LV tract.
