Critical Assessment of Noninvasive Prenatal Testing: Before or after Anomaly Scan

Combined first trimester screen or noninvasive prenatal testing or both.

Assessment of Progressive Pathophysiology After Early Prenatal Diagnosis of the Ebstein Anomaly or Tricuspid Valve Dysplasia.

In fetuses with Ebstein anomaly or tricuspid valve dysplasia (EA/TVD), poor hemodynamic status is associated with worse neonatal outcome. It is not known whether EA/TVD fetuses with more favorable physiology earlier in gestation progress to more severe disease in the third trimester. We evaluated if echocardiographic indexes in EA/TVD fetuses presenting <24 weeks of gestation are reliable indic...

Comparison of noninvasive prenatal testing of cell‐free DNA in maternal blood and amniocentesis for evaluation of aneuploidy

Background: The aim of this study was to compare noninvasive prenatal testing (NIPT) of cell‐free DNA in maternal blood and amniocentesis in the diagnosis of aneuploidy. This study was designed to evaluate sensitivity, specificity, accuracy, positive predictive value and negative predictive value of NIPT for detection of aneuploidies compared gold standard test of amniocentesis. Materials and m...
