Myocardial performance index in fetal anemia

Abstract

LV myocardial performance not only remains preserved but also is actually enhanced in cases of moderate/severe fetal anemia.

Assessment of fetal myocardial performance index in women with pregestational and gestational diabetes mellitus

“…recently reported that worsening fetal anemia was associated with a reduction in the left ventricular MPI value. They concluded that left ventricular performance not only remained preserved but also was augmented in cases of moderate and severe anemia . Moreover, in a subsequent study they showed that MPI value was elevated following intrauterine transfusion .…”

Time Interval Measurements of the Ductus Venosus During the Early Second Trimester of Pregnancy: Reference Ranges and Clinical Application

“…In fetal anemia, myocardial performance increases to maintain sufficient tissue perfusion . Hecher et al reported that the ductus venosus blood flow velocities increased significantly; however, indices such as the peak velocity index and pulsatility index for veins were not different compared with healthy fetuses.…”

Fetal myocardial index during labor

“…2 It has been used in perinatology to evaluate systolic and diastolic dysfunction in fetuses with twin to twin transfusion syndrome, preterm premature rupture of membranes, fetal anemia and intrauterine growth restriction. [3][4][5][6][7][8][9] Additionally, MPI has also been used to evaluate cardiac function in fetuses of diabetic mothers and in fetuses with arrythmias. [10][11][12][13][14] Many of these studies have found significant increases to MPI in these fetuses.…”

“…[10][11][12][13][14] Many of these studies have found significant increases to MPI in these fetuses. [3][4][5][6][7][8][9][10][11][12] There is very little information available about MPI in term fetuses in labor. Labor can be a potentially stressful environment for a fetus and hypoxemia and even acidosis…”
