Objective – To identify the risk factors associated with the occurrence of fetal heart disease and to characterize the fetal heart diseases diagnosed in the prenatal period. Methods – This is a quantitative, descriptive and retrospective study performed at the Prenatal Outpatient Service of Fetal Medicine of a university hospital in the city of São Paulo (SP). The sample consisted of 36 pregnant women with fetuses with congenital heart disease. Results – The age of the pregnant women ranged from 15 to 49 years, with emphasis on the age group between 20 and 29 years (50%). A high index of drug exposure (58%) and family history of congenital anomalies (42%) were observed among the pregnant women studied. Regarding fetal heart diseases, 15 (42%) fetuses had isolated malformations and 21 (58%) were associated with malformations in other organs and systems, including multiple anomaly syndromes. Conclusions – The results suggest that maternal age, family history of congenital anomalies and teratogenic exposures may be considered risk factors associated with the development of pregnancies with fetuses with cardiopathies, most of them associated with multiple anomaly syndromes.
