title: Prenatal echocardiographic diagnosis of congenital heart disease: comparison of past and current results.
abstract: The increased experience in interpretation of fetal echocardiographic images may change the accuracy of fetal echocardiography in diagnosing fetal heart defects. We thus decided to evaluate the specificity and the sensitivity of our fetal echocardiographic examinations in diagnosing congenital heart disease, focusing especially on the outcome of complex cardiac pathologies. Between October 1999 and July 2003, 642 fetuses were followed until birth and underwent a postnatal reassessment of the cardiovascular system in our institution. These cases constitute our cohort. The postnatal reassessment was mainly done by echocardiography; some cases also had angiography. In case of intrauterine or postnatal death, an autopsy was performed. The prenatal and postnatal diagnoses were compared, and specificity and sensitivity of fetal echocardiography for congenital heart pathologies were determined. Among 45 affected pregnancies, 31 cases had complex and 14 had significant cardiac defects. The sensitivity of fetal echocardiography for cardiac anomalies was 93.3%; the specificity was 100%. Compared to our previous study, the sensitivity was remarkably improved (in our previous study sensitivity was 78% and specificity 100%). Echocardiography is a very useful and reliable tool in the evaluation of the fetal cardiovascular system, and has high sensitivity and specificity for congenital heart diseases.
