Diagnosis and classification of fetal congenital heart disease by echocardiography / 中华超声影像学杂志

ABSTRACT

Objective To investigate the common types of fetal cardiac malformations and complicated malformations,and to assess the value of classifying on these types.Methods 3201 pregnant women were undergone with fetal echocardiography (FECG),239 fetuses of them were diagnosed to be suffered with congenital heart disease(CHD),and 8 cases were one of twins with abnormal heart confirmed by FECG.All new-births were examined by echocardiography within half year after their births.Results 155 complex CHD in 239 fetuses were diagnosed by FECG,in them the common malformations were in turn 59 cases with diagnosed univentricular heart,29 cases with double outlet right ventricle,19 with atrio ventricular septum defect,12 with tetralogy of Fallot or quinalogy of Fallot,11 with persistent truncus arteriosus,6 with right ventricular dysplasia syndrome,6 cases transposition of the great vessels.100 cases were induced labor,41 of them were comfirmed by pathology.16 fetuses were born,123 cases were being pregnanted or un-followed up.Conclusions Complex and multi-malformation were common in fetal cardiocascular abnormalities.Diagnosing rate of fetal CHD(FCHD) in our enroll fetuses was 7.47 ％,rate of complex CHD vs CHD was 64.85 ％.According different types of FCHD,able to be operated or not after birth,surgery methods,as well as prognosis evaluations,all FCHD cases were classified into three subtypescurable type,curable palliative type and untreatable type.This newly viewpoint will help pregnant women and their family to make reasonable selection.
