Among 847 cases with fetal diagnosis of congenital heart disease, 28.9% were terminated; of 602 continuing pregnancies, 11.9% died in utero, 43% died postnatally, and 45% survived.

Fetal diagnosis of complex congenital heart disease is associated with significant fetal and postnatal loss, with associated anomalies and heart failure acting as negative prognostic factors.
OBJECTIVES: To analyse the evolution and outcome in utero and after birth of infants with a fetal diagnosis of congenital heart disease. DESIGN: Inclusion criteria were the fetal diagnosis of congenital heart disease, confirmed postnatally or postmortem, and a complete follow up in utero and after birth. SETTING: 20 centres operating prenatal echocardiographic screening. PATIENTS: 847 cases were included in the study. Gestational age at diagnosis ranged from 15-39 weeks; in 370 cases (43.7%) the diagnosis was made before 24 weeks' gestation. RESULTS: 245/847 cases (28.9%) were terminated during pregnancy, 227 following early diagnosis; 128/245 cases (52. 2%) had associated anomalies and 117/245 (47.8%) had serious congenital heart disease. Of the remaining 602 cases that continued the pregnancy, 72 (11.9%) died in utero, 259 (43%) died postnatally (83 after surgery or invasive procedures), and 271 infants (45%) survived and presently range in age from 18 months to 13 years old. The mortality rate was higher in cases with associated extracardiac or chromosomal anomalies (68% and 74% of cases continuing pregnancy, respectively), and in cases with heart failure and complex cardiac defects. CONCLUSIONS: The data confirm a relevant fetal and postnatal loss in cases with complex congenital heart disease, and major clinical use of prenatal diagnosis in the management of ductus dependent anomalies. Negative prognostic factors for the outcome were associated anomalies and heart failure.
Fesslová et al. (Mon,) conducted a cohort in Congenital heart disease (n=847). Fetal diagnosis of congenital heart disease was evaluated on Evolution and outcome in utero and after birth (termination, in utero death, postnatal death, survival). Among 847 cases with fetal diagnosis of congenital heart disease, 28.9% were terminated; of 602 continuing pregnancies, 11.9% died in utero, 43% died postnatally, and 45% survived.
