Abstract

Objective. To evaluate the accuracy of prenatal diagnosis of heart defects on the basis of comparison of pre- and postnatal diagnoses. Materials and methods. A total of 450fetuses with heart defects were examined in seven steps at the Clinical Hospital of Mother and Child group of companies in Moscow, from January to December 2018. The fetuses were examined by Voluson E6, E8, and E10 ultrasound machines transabdominally and transvaginally using multi- frequency convex and intracavitary transducers. Pre- and postnatal diagnoses of heart defects were compared according to echocardiography (EchoCG) data. Results. The study included 429 cases with confirmed diagnoses. Isolated ventricular septal defect (VSD) was diagnosed in 297fetuses. Prenatal diagnosis of VSD was confirmed in 84% of cases postnatally. The rest of the heart defects were detected in 132 fetuses. The comparison of pre- and postnatal EchoCG data showed the highest percentage of coincidence in the diagnosis of 14 diseases and reached 100%. The most frequent pathologies were common atrioventricular canal (CAVC), double-outlet right/left ventricle with malposition of great arteries (DORV/DOLV with MGA), and hypoplastic left/right heart syndrome (HLHS/HRHS). The highest percentage (60%) of difference in diagnosis was observed in diagnosing Fallot’s tetrad (FT) and aortic coarctation (AC). Conclusion. Prenatal evaluation of heart defects in 7 steps can help to achieve high accuracy in diagnosing and combine pre- and postnatal approaches to diagnosis formulation.
