TLDR
Fetal atrioventricular plane displacement before and after IUT is measured to compare these measurements with previously established reference ranges and to measure fetal myocardial function and adaptation.
Abstract
Maternal red blood cell alloimmunization during pregnancy can lead to hemolysis and various degrees of fetal anemia, which can be treated with intrauterine blood transfusion (IUT) to prevent adverse outcomes. Knowledge about fetal myocardial function and adaptation is limited. The aim of the present study was to measure fetal atrioventricular plane displacement before and after IUT and compare these measurements with previously established reference ranges.
