Search for: [Abstract = "d sensitivity of 37,14% with specificity of 95,61%. Lowering of NT cut\-off to the 95th percentile caused the increase in sensitivity to 60% at the cost of lowering specificity to 89.51%. Basing on the most common ultrasound pictures of ventricular inflows 4 patterns were defined at the level of 4CV. At the level of 3VTV 6 patters were described.ConclusionsIsolated late first\-trimester tricuspid regurgitation \(TR\) is a poor screening tool for detecting aneuploidy and CHDs in euploidy. TR in combination with other ultrasound markers of aneuploidy is the strongest predictor of chromosomal aberrations. Absent DV detected, 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."]
