Objectives: The size, shape, and contractility of the heart's atrial chambers have not been evaluated in fetuses with growth restriction (FGR) or who are small-for-gestational-age (SGA) as defined by the Delphi consensus protocol. This study aimed to examine the atrial chambers using speckle tracking analysis to identify any changes that may be specific for either growth disturbance.
Methods: Sixty-three fetuses were evaluated with an estimated fetal weight <10th percentile who were classified as FGR or SGA based on the Delphi consensus protocol.
