Abstract：Objective To investigate the effects of two-dimensional and three-dimensional ultrasound in screening fetal congenital cardiovascular malformation and improve the diagnostic efficiency.Methods Used the random sampling and retrospective study method,from January 2013 to April 2016,35 women of suspected fetal cardiovascular malformations in our hospital for treatment were selected as the research object,all women were giving the two-dimensional,three-dimensional ultrasound and pathological examination that the results were compared and analyzed,and were given to determine the effectiveness of diagnosis.Results In the 35 women,pathological examination revealed 102 abnormal cardiac conditions that 35 were abnormal atrioventricular septal,28 were abnormal ventricular connections,25 were abnormal atrioventricular connections,14 were abnormal arterial trunks.However,the correct diagnosis rate of various types of cardiovascular malformations by the two-dimensional ultrasound combined the three-dimensional ultrasound were higher than that of two-dimensional ultrasound (P＜0.05).And the diagnosis sensitive,specificity,positive predictive value and negative predictive value of fetal congenital cardiovascular malformation by the two-dimensional ultrasonography were 84.9％,50.0％,96.6％ and 16.7％,and were 97.0％,100.0％,100.0％ and 66.7％ by the two-dimensional ultrasound combined the three-dimensional ultrasound that compared were all significantly difference (P＜0.05).Conclusion Ultrasonography in diagnosis of fetal congenital cardiovascular malformation has important significance,two-dimensional ultrasound combined the three-dimensional ultrasound has an objective assessment of cardiac morphology,it can improve the level of diagnosis that has good application values.
