Background: A retrospective analysis of the records of all the patients of heart disease with pregnancy at AIIMS, New Delhi, India, to find out the maternal and fetal outcome.
Materials and methods: A retrospective analysis was carried out of 100 pregnancies in women with heart disease who delivered at ≥28 weeks of gestation from July 2009 through August 2012.
Results: Cardiac disease was found to complicate 3.8 % of pregnancies. Rheumatic heart disease (n = 64, 64 %) was the predominant cardiac disease. Congenital heart disease was found to complicate 36 pregnancies (n = 36, 36 %).Cardiac complications were seen in 32 (32 %) and fetal complications in 18 (18 %) pregnancies. Fewer cardiac and postpartum complications were present in NYHA class I/II patients compared to NYHA III/IV patients (P < 0.05). Pregnancy outcome was better in rheumatic heart disease patients who had undergone cardiac intervention prior to pregnancy (n = 29, 45.2 %) compared to those whose heart disease remained uncorrected (n = 35, 54.8 %) but the difference was not statistically significant. There was one maternal mortality in a patient with Eisenmenger syndrome. Two of the newborns of the 17 women who had received anticoagulants had features of warfarin embryopathy.
Conclusion: Pregnancy in women in NYHA class III/IV is associated with significantly higher maternal morbidity and cardiac interventions before pregnancy, when indicated may improve pregnancy outcome.
