OBJECTIVE: To evaluate the frequency of fetomaternal outcome of pregnancy with Mitral stenosis admitted in Civil Hospital Karachi. METHODS: It was a two years descriptive study done in the Department of Obstetrics and Gynaecology Civil Hospital Karachi. All pregnant women with a known or newly diagnosed Mitral stenosis on echocardiography were included in the study. History was taken regarding age, parity, gestational age (calculated by ultrasound) and complaints. Mode of delivery and Maternal mortality noted. Foetal outcome was analyzed by birth weight and Apgar score. RESULTS: A total of 101 patients meeting the inclusion criteria were enrolled in the study. The ages of the women ranged between 20-29 years (69%) and 81% were multigravidas. Vaginal delivery occurred in 67 (66.3%) women and 78.3% were term pregnancies. Preterm deliveries were 21.8% and 27.7% newborns were low birth weight. APGAR score <7 was found in 14.9% of neonates and 9 babies had intrauterine death. Low ejection fraction<55% was diagnosed in 20(13.9%) women and Maternal mortality was found in two cases. CONCLUSION: Heart disease in pregnancy is associated with significant morbidity, it should be carefully managed in a tertiary care hospital to obtain optimum maternal and foetal outcome.
