In study 1\- 1075 cases were analyzed, in study 2\- 5811, and in study 3\- 1084. In study 1 \(assessment of tricuspid flow\) and in study 2 \(evaluation of DV flow\) the following parameters were analyzed\: \-maternal age in subgroups of euploidy and aneuploidy\;, \-crown\-rump length in subgroups of euploidy and aneuploidy\;\-frequency of primary and secondary markers of aneuploidy including cardiovascular ones \(nuchal translucency, nasal ossification, tricuspid flow, DV flow, number of umbilical arteries\) in subgroups of euploidy and aneuploidy\;\-coincidences of primary and secondary ultrasound markers of aneuploidy\;\-fetal heart rate in subgroups of euploidy and aneuploidy\;\-frequency of extracardiac and cardiac defects in subgroups of euploidy and aneuploidy\;\-sensitivity and specificity of tricuspid regurgitation \(TR\) and abnormal DV flow for detecting major aneuploidy and CHDs in euploidy.In the study 3 concerning first\-trimester screening for CHD descriptive statistics was applied. Next sensitivity, specificity, positive and negative predictive values and diagnostic accuracy of screening methods based on four\-chamber view and three\-vessel and trachea view in color mapping were calculated. Basing on obtained results, patterns of the most common ultrasound"]
