Material and Methods: A retrospective analysis of 222 pregnancies of women with cardiac disease who received antenatal care and were delivered in the obstetrics department of a tertiary care center between 1997 and 2012 was carried out. Perinatal and maternal outcomes were evaluated according to the type of the heart diseases and cardiac status of the patients according to the New York Heart Association (NYHA) functional classification. Results: The percentage of rheumatic and congenital heart diseases were 76.1% and 15% respectively. The distribution of the patients according to the NYHA functional classification were 117 (52.7%), 87(39.1%) and 18(8.2%) for NYHA classes I, II and III-IV respectively. Two cases of maternal mortality were recorded. Maternal morbidity was observed in 31 (13.9%) cases. seven cases of perinatal mortality (3.1%) were also recorded. There were no statistical significance between NYHA Stage I-II and Stage III-IV groups in terms rates of cesarean, vacuum or forceps deliveries (p=0.605), whereas mean values birth weight, gestational age at delivery, mean birth weight, incidence of perinatal morbidity, maternal morbidity and mortality were significantly higher in NYHA Stage III-IV group (p=0.023, 0.001, 0.035, 0.001 ve 0.024 respectively). Conclusion: Rheumatic heart diseases constitute the most predominant group of cardiac diseases to complicate pregnancies in developing countries. The majority of patients are found to be in favorable functional classification and maternal morbidity strongly correlates with maternal cardiac functional classification.
