In a period of two years were performed 759 ECOF in pregnant women who were referred to the National Children’s Hospital. Data collected included the following items: maternal age, gestational age, number of pregnancies, births, cesarean sections, abortions, site from which they came, maternal pathology associated, family history of congenital heart disease, final diagnosis made by a pediatric cardiologist. Most mothers were referred for gestational diabetes. In 21% of cases, cardiac abnormalities were found. The age of mothers ranged from 13 to 46 years. The largest group was between 20-40 years (83.7%). During the second trimester were made 49% of the examinations and the vast majority at 24 weeks gestation. In the third trimester was 47.4% performed the most examinations at 34 weeks gestation. 29% of mothers were primiparous and 24% second quest. The most frequently encountered cardiac disorders were especially supraventricular extrasystoles with 20%, followed by hypoplastic left heart syndrome with 18% and ventricular septal defect with 16.4%. In conclusion, the percentage of cardiac abnormalities detected with ECOF remains very low because it only refers to mothers with high risk and those at low risk were not performed in the obstetric ultrasound the four-chamber view and the study of the outflow tracts of the heart.
