Abstract:
To compare fetal Tei index before, immediately after and 30 min after cordocentesis for prenatal diagnosis.Pregnant women undergoing prenatal diagnostic cordocentesis in the early mid-trimester underwent measurement of the fetal Tei index of both right and left ventricles just before cordocentesis , immediately after and at 30 min after the procedure.A total of 143 singleton women underwent cordocentesis at a median gestational age of 19 weeks (range 16-23). The most common indication was fetal risk of beta-thalassemia/hemoglobin E disease (42%, 60 cases). Immediately after cordocentesis , fetal Tei index and all its components at both ventricles were significantly altered when compared with the baseline values (p
