Role of global sphericity index in evaluation of fetal cardiac remodeling in late onset fetal growth restriction and small for gestational age fetuses.

Introduction: Fetal growth restriction (FGR) fetuses develop cardiovascular remodeling and dysfunction and, in this process, heart first compensates by changing its shape from ellipsoid to spherical and then cardiac dysfunction follows. Our aim was to evaluate global sphericity index (GSI) after 32 weeks of gestation to evaluate this change in cardiac shape and correlate GSI changes associated with fetal growth abnormalities.

Materials And Methods: This was a prospective study conducted at 32-38 weeks of gestation.
