Rev. chil. obstet. ginecol. [online]. 2010, vol.75, n.4, pp.234-239. ISSN 0048-766X.  http://dx.doi.org/10.4067/S0717-75262010000400004.

Background: In Chile, congenital malformations are the first cause of early neonatal mortality, the congenital heart defects its the main factor. The incorporation of antenatal echocardiography is very helpful in your research early. Objectives: To evalúate prenatal echocardiography as a diagnosis test and their concordance with postnatal echocardiography. Methods: We analyzed pregnancy who were derived to the Hospital de Niños Dr. Roberto del Rio, between April 2004 and April 2008, where studied because suspicion of having congenital heart defects with subsequent neonatal control. Results: 188 pregnancy were evaluated either with a diagnosis of congenital heart defect or with normal echocardiography. The mean gestational age of derivation was 32 weeks, the main causes the suspicion of congenital heart defect on routine obstetric examination. When being studied as diagnosis test it was obtained a sensitivity of 100% and a specificity of 40% with a modérate concordance between both echocardiographies. When analyzing with the diagnosis test prenatal echocardiography, it was obtained a sensitivity of 100% and a specificity of 89% of the review, when evaluated as general heart defect, with a very good concordance between it and the postnatal examination. Discussion: There is a late referral and prenatal diagnosis of congenital heart defect at national level, being important to train obstetricians who perform this screening. Prenatal echocardiography performed by cardiologists at our center is a reliable diagnosis tool with a very good concordance with postnatal echocardiography.
