Purpose To explore the application value of micro-blood flow imaging(MV-Flow)combined with LumiFlow in obtaining the standard views of fetal heart at 11-17+6 weeks.Materials and Methods A total of 63 normal pregnant women in first and second trimesters who underwent fetal echocardiography in the PLA General Hospital from July 2022 to August 2023 were retrospectively examined by color Doppler flow imaging(CDFI)and MV-Flow combined with LumiFlow to obtain 8 diagnostic views recommended by the International Society of Ultrasound in Obstetrics and Gynecology,and researchers A and B scored diagnostic elements displayed in each section of different modes.The mean value of each diagnostic section element score was calculated to analyze the success rate of all diagnostic sections from the two different pattern diagrams,and to compare the success rate and scores of the two different modes,respectively.Results A total of 63 pregnant women were examined by fetal echocardiography for 66 times,and the success rates of MV-Flow combined with LumiFlow in upper abdomen view,four chamber view and aortic arch view respectively were 98.48%,98.48%and 96.97%,which was significantly higher than those of CDFI(χ2=5.143,8.100,6.125,P<0.05),and the success rates of three-vessel trachea view and left ventricular outflow tract view were 39.40%and 43.94%,which were significantly lower than those of CDFI(χ2=13.885,7.579,P<0.05).There was no difference between MV-Flow combined with LumiFlow and CDFI in the overall score of ductal arch view,vena cave view and all sections(Z/t=-1.56,-1.77,-4.10,P>0.05).The scores of MV-Flow combined with LumiFlow were significantly higher than those of CDFI in upper abdomen view,four chamber view and aortic arch view(t=-5.14,-6.08,-6.63,P<0.001),and were significantly lower than those of CDFI in left and right ventricular outflow tract view and three-vessel trachea view(Z=-4.61,-4.06,-2.93,P<0.001).Conclusion MV-Flow combined with LumiFlow has more advantages than CDFI only in the display of upper abdomen view,four chamber view and aortic arch view,which can be used as an effective supplement to blood flow imaging technology in early fetal heart screening.
