[Fetal echocardiography efficiency. Clinical experience].
BACKGROUND
Congenital heart disease diagnostic has a high diagnostic precision with fetal echocardiography. This study has been reported in populations with high risk and with a sensibility of 86 to 99% and specificity of 91 to 100%.


OBJECTIVE
To know sensibility and specificity of fetal echocardiography in high-risk pregnancies, and to describe types and frequency of congenital heart disease in utero.


METHODS
229 files of pregnant women with high-risk factors, more than 15 weeks of gestation, and at birth cardiovascular exam were analyzed. This analysis was made by means of simple frequencies, sensibility, specificity, positive and negative predictive value, and truth index calculation.


RESULTS
We found 62 (27%) cases with fetal heart disease. Mean of maternal age was 27 +/- 5.5 years, and of gestational age 31 +/- 5 weeks. Risk factors that require study were: four-chamber abnormality in routine ultrasound, dysmorphy, fetal bradicardia, and poll and oligohydramnios. There were 55 (88.7%) high-risk heart diseases, and most frequent were Ebstein's anomaly, unique ventricle, hypoplastic left ventricle syndrome, and tumors. Sensibility was 98.41%, specificity was 97.59%, positive prognostic value was 97.59%, and negative prognostic value was 99.39%.


CONCLUSIONS
Fetal echocardiography has a high diagnosis certainty in our hospital unit, thus, it has to be a normal prenatal exam in pregnant women with high-risk factors.
