Abstract

Purpose: Role of prenatal ultrasonographic in diagnostic of
congenital heart defects
Subjects and methods: Descriptive study on 98 fetuses diagnosed
congenital heart defects (CHDs) from August 2018 to September 2020 at
National Obstetric and Gynecology. 50 cases with live birth, 22 cases of
pregnancy termination, 4 cases of perinatal mortality, 22 cases of losing
follow-up. The patient was performed an prenatal fetal heart ultrasound
and follow the outcome.
Result: The mean maternal age was 28.5 ± 9.4 yrs old, the mean
gestational age at the time of prenatal diagnosis of CHD was 28 ± 6,4
weeks. CHDs accounts for a high proportion on prenatal ultrasound:
ventricular septal defect (VSD), atrioventricular septal defect (AVSD) and
the double outlet right ventricle (DORV) account for 14-15% of CHDs.
The mild CHD account for 27.6%, critical CHD was 72.4%. Accuracy
of prenatal echocardiography diagnosis was 88%. The severity of CHDs
prenatal ultrasound affects pregnancy outcome (p<0.05).
Conclusion: Fetal echocardiography has high accuracy in prenatal
diagnosis of CHDs. The severity of CHDs in prenatal ultrasou impact on pregnancy outcome.
