Abstract:
Objective To investigate the value of ultrasound in diagnosis of fetal heart malformation at 11-13+6 weeks gestation.Methods A total of 70 pregnant women were selected,based on the results of induction of labor and postnatal imaging examination, the effect of ultrasound on fetal heart abnormalities in 11-13+6 weeks was observed.The display of cardiac malformations with different cuts was compared.Results In 70 fetuses with cardiac malformations, malformation types included tetralogy of Fallot, double outlet right ventricle, complete endocardial cushion defect, transposition of the great arteries, persistent truncus arteriosus, aortic arch, venous drainage.Ultrasound diagnosis of 64 cases of fetal cardiac malformations, the diagnostic accuracy rate was 91.4%.Among them, the highest proportion of tetralogy of Fallot (42.9%), venous drainage was the lowest (2.9%).The diagnostic rate of 4CV+3VVT ultrasound for fetal heart malformation was the highest(91.4%), which was significantly higher than 4CV+VOTV(72.2%), 4CV+(AR-SAV)(68.6%) and 4CV, the differences were statistically significant (x2=7.643,5.324,4.447,all P<0.05).The diagnostic accuracy of 4CV+3VV ultrasound for fetal heart malformation was 88.6%, which was significantly higher than 4CV+ (AR-SAV) and 4CV section, the differences were statistically significant (x2=6.343,4.011,all P<0.05).Conclusion Ultrasound can be used to detect fetal heart malformation at 11-13+6 weeks gestation, among them, the accuracy of 4CV+3VVT ultrasound section is the highest.
