Abstract:
Objective To explore the value of transvaginal ultrasound five-view method for diagnosing fetal congenital heart disease(CHD)in early pregnancy of high-risk pregnancy.Methods Totally 428 singleton fetuses at 11-13+6 weeks of gestation in high-risk pregnancies were prospectively enrolled.Fetal cardiac examinations were performed using two-dimensional grey scale imaging combined with CDFI via transabdominal ultrasound method,transvaginal ultrasound five-view method(upper abdominal transverse view,four-chamber view,three-vessel and trachea[3VT]view,ventricular outflow tract view and bilateral subclavian artery view)and transvaginal ultrasound two-view method(four-chamber view and 3VT view).Taken results of pregnant metaphase or late pregnancy fetal echocardiography,post-abortion pathology or postnatal neonatal echocardiography as gold standards,the diagnostic performances of the above 3 methods for diagnosing fetal CHD in early pregnancy were compared.Results CHD was diagnosed in 120(120/428,28.04％)fetuses.Transvaginal ultrasound five-view method made 11 false positives and 19 false negatives,with sensitivity,specificity,positive predictive value and negative predictive values for diagnosing fetal CHD in the first trimester of high-risk pregnancy of 84.17％,96.43％,90.18％and 93.99％,respectively,which were all significantly higher than of transvaginal ultrasound two-view method(70.83％,91.88％,77.27％and 88.99％)and transabdominal ultrasound method(72.50％,91.23％,76.32％and 89.49％;all P＜0.05).Conclusion Transvaginal ultrasound five-view method could be used to effectively diagnose fetal CHD in the first trimester of high-risk pregnancy.
