Purpose: Maternal cardiac disease is one of the major causes of non-obstetric maternal morbidity and mortality. In the treatment of cardiovascular diseases during pregnancy, it is important to prescribe the drugs that control maternal disease and to minimize potential drug-related risk to the fetus. The aim of this study is to evaluate the teratogenic safety of cardiovascular drugs in pregnancy. Materials and Methods: We collected data of pregnant women who used drugs for cardiovascular disorders and admitted to our unit for drug analysis between 2014 and 2018. Teratology Information Service assessed the teratogenic risk of drugs. After delivery, a follow-up was conducted with families to obtain the presence of any congenital malformations or adverse neurodevelopmental effects in the infant.  Results: Use of ramipril in the first six weeks of pregnancy resulted in spontaneous abortus at the 10th week. Use of warfarin in the first 12 weeks resulted in exitus at the postnatal fourth day. Telmisartan exposure in the first six weeks resulted in intrauterine death in the 18th gestational week. Conclusion: Drugs acting on renin-angiotensin system should be discontinued when pregnancy is detected. Warfarin is contraindicated for use in pregnancy except mechanical heart valve pregnancies with high risk of thromboembolism, as it leads to coumarin embryopathy and nervous system anomalies in the first trimester exposures. Pregnant women should be directed to the teratogenic drug analysis and evaluated for possible increase in drug-related congenital malformation risks at early gestational period. Teratogenic risk counselling and follow-up ensures reliable data on drug safety during pregnancy.
