This prospective study was conducted to evaluate the outcome of pregnancies in women with congenital heart diseases. In this study 50 pregnant women age between 20-45 years with congenital heart diseases were included. Twenty two (44%) were presented with atrial septal defect, 12(24%) with ventricular septal defect, 5(10%) were with patent ductus arteriosus, 6(12%) with Fallot's tetralogy, 2(4%) with pulmonary stenosis, 2(4%) with Eisenmenger syndrome, 1(2%) with dextrocardia. Shortness of breath (60%) was the main presenting complaint. Normal vaginal delivery (52%) was done in majority of cases. Spontaneous abortion occurred in 16% of pregnancies. Major complications were heart failure 16%, arrhythmias 21%, cardiovascular mortality 4%, preeclampsia 4%, and eclampsia 2%. Premature birth 16%, fetal demise 4%, neonatal death 2% and cardiac anomaly at birth 2% were also observed. The outcome of pregnancy in women with congenital heart diseases is favourable with considerable maternal and neonatal complications.
