Small for gestational age (SGA) fetuses have an increased risk for adverse outcome. Placental insufficiency leads to changes in the circulation, with secondary adaptation of the fetal heart resulting in changed cardiac deformation. This deformation can be measured with 2D speckle tracking echocardiography (2D‐STE). SGA is antenatally often undiagnosed. The measurement of deformation changes in the fetal heart might help in the prediction of SGA and identify fetuses in need of more intensive surveillance.

在小于胎龄的胎儿中，由异常应变值确定的右心室功能障碍先于明显的生长受限。

小于胎龄 (SGA) 的胎儿出现不良结局的风险增加。胎盘功能不全导致循环改变，胎儿心脏的二次适应导致心脏变形的改变。这种变形可以用 2D 斑点跟踪超声心动图 (2D-STE) 测量。SGA 在产前常常未被确诊。胎心变形变化的测量可能有助于预测 SGA 并识别需要更密集监测的胎儿。
