Search for: [Abstract = in coincidence with thickened nuchal translucency \(NT\) can be helpful in screening for Turner syndrome and differentiating this anomaly from other aneuploidies. Isolated reverse a\-wave in DV flow \(revDV\) was found only in euploidy and trisomy 21. Any coincidence of revDV with other ultrasound markers of aneuploidy is a common feature of major trisomies. Isolated revDV is a poor screening tool for trisomy 21 and CHD in euploidy. Four\-chamber view and three\-vessel and trachea view in color mapping can be easily adopted in the routine first\-trimester screening scan protocol. The combined application of these two cardiac views shows the most effective screening performance for CHD in the late first\-trimester.]
