The aim of this study was an analysis of cardiac assessment in the first trimester, their outcomes, and comparison with literature data. Five cases were analysed from the year 2014. The exams were performed between 11-13 + 6 weeks. The analysis confirmed that the detection of CHD in 1 st trimester was possible and was verified by an early fetal echocardiogram. The most common symptoms of abnormal heart images in the early screening assessment were: axis, heart size and color Doppler assessment of the chambers and V sign. The outcome of pregnancies with early detection of fetal heart defects was poor. There was only one surviver
