Changes in fetal myocardial performance index following intravascular transfusion: preliminary report.

Objective: To investigate the changes in fetal left ventricle myocardial performance index (MPI) following intrauterine intravascular transfusion (IUT).

Methods: Prospective study, including 25 IUT performed in 13 singleton pregnancies with maternal Rh D alloimmune disease. Left ventricle MPI was evaluated prior to transfusion and repeated 24 h after each procedure.

Myocardial performance index in fetal anemia.

Objective: The objective of the study was to examine the correlation between fetal myocardial performance index (MPI) and hemoglobin (Hb) levels.

Methods: It is a prospective study involving singleton pregnancies at risk of fetal anemia as a result of maternal anti-D alloimmune disease. Right and left ventricle (LV) MPIs were evaluated by ultrasound up to 72 h before cordocentesis.

Longitudinal reference ranges for fetal ultrasound biometry in twin pregnancies.

Objective: The purpose of this study was to establish longitudinal reference ranges for fetal ultrasound biometry measurements and growth parameters in twin pregnancies.

Method: A total of 200 uncomplicated twin pregnancies before 21 weeks of gestation were recruited for this prospective, longitudinal study. Women who abandoned follow-up, pregnancies with unknown outcomes or pregnancies with complications were excluded.
