Abstract:
Objective To evaluate the value of two-dimensional strain imaging in assessing right ventricular function of recipient fetus in TTTS pregnancies.Methods Sixteen TTTS pregnancies and 19 normal monochorionic diamniotic pregnancies(controls) were included.Doppler studies of the umbilical artery,umbilical vein,ductus venosus,middle cerebral artery,atrioventricular valve and semilunar value were recorded in both fetus,and myocardial performance index of both ventricles was calculated.Longitudinal peak systolic strain of right ventricular were calculated and compared between recipient fetus and other fetus.Results Cardiothoracic ratio and myocardial performance index of right ventricular showed significant differences between recipient fetus and controls.Right ventricular strain was decreased in recipient fetus compared with controls.Conclusions Two-dimensional strain imaging can be used to evaluate right ventricular myocardial function in the recipient fetus of TTTS.
