The authors present a estudy related to the prenatal detection of congenital heart diseases. The congenital anomalies (CA) are morphological or functional disorders of prenatal origin, present since the birth, even they can be detected later on, during their lifes. They constitute the second cause of infantile death in our country, following, prenatal diseases (prematurity, perinatal infections, etc.) The most severe CA have relevance for the health and require usually clinical a surgical treatment. Congenital cardiopaties (CC) are the most frequent and represent a great impact in the mobimortality both neonatal and pediatric. Foetal echocardiography is a sensitive and specific method of investigation for prenatal detection of cardiac malformations. Experience has shown that echocardiographic screening can demonstrate, the presence of probably various cardiac disease in the foetus as early as 18-20 th weeks of pregnancy. It is recommended that screening should be carried out as part of other forms of obstetric ultrasonic screening. Our aims were to analyze the characteristies of the pregnants at risk factors to CC. To determine the associated factors to the fetal pathology of the fetal electrocardiogram, and to correlate the postnatal diagnosis by cardiac echodoppler, which impoves neonate survival and reduces morbidity. The results obtained are detailed in the article (AU)
