ABSTRACT

We present 119 echocardiographies in 90 high-risk pregnancies, 20 to 40 weeks gestational age. There were found 18 fetuses with abnormal examinations (20%), six of them with structural alteration (6.6%), and 14 arrhythmias (15.5%). The diagnostic correlation in structural alterations with a sensibility of 83% and 100% specificity, and 100% of sensibility and specificity in arrhythmias. The importance of antenatal diagnosis in cardiac malformations and arrhythmias is described.
