Foetomaternal Outcomes in Pregnant Women with Corrected vs Non corrected Heart Disease: A Cross-sectional Analysis at a Tertiary Care Institute of Eastern India

Abstract

Introduction: Cardiac disease in pregnancy remains a major concern, particularly in developing countries like India. Pregnancy in women with heart disease increases the risk of maternal and foetal complications. Approximately 1% to 4% of pregnant women have concomitant cardiac disease. Aim: To examine the foetomaternal outcomes of pregnant women in the corrected vs. non corrected heart disease groups. Materials and Methods: This was a cross-sectional study conducted in the Department of Obstetrics and Gynaecology at IPGME&R, Kolkata, West Bengal, India, from February 2020 to July 2021. A total of 50 pregnant women were included in the present study, with 25 in the corrected heart disease group and 25 in the non corrected heart disease group. Foetomaternal outcomes, including intrapartum complications, maternal intensive care unit admission, mode of delivery, and foetal complications, were observed. Comparative analyses were conducted using the Student’s t-test and Chi-square test. The p-values <0.05 was considered statistically significant. Results: Data from the present study showed that out of a total of 50 pregnant women with heart disease, the majority (60%) were young (≤25 years). Approximately 48% of women were in their second pregnancy. The most common cardiac lesion in the corrected group was closure of Atrial Septal Defect (ASD) in 8 (16%) cases, while in the non corrected group, the most common was mitral regurgitation in 11 (22%) cases. In the corrected heart disease group, 15 (30%) had a caesarean section and 10 (20%) delivered vaginally, whereas in the non corrected group, 17 (34%) had a caesarean section and 8 (16%) delivered vaginally. Adverse cardiac events occurred in 2 (4%) of the corrected group, whereas 11 (22%) were observed in the non corrected group (p-value=0.0088, significant). Preterm birth and low birth weight babies were more common in the non corrected heart disease group (p-value=0.0449, significant). Conclusion: The study concludes that most women with cardiac disease are young. Compared to the Corrected Group of Heart Disease (CGHD), the non corrected group of pregnant women are more likely to experience severe cardiac complications and require admission to the intensive care unit. The foetomaternal outcome is better in the corrected group. Successful management of pregnant women with heart disease requires a comprehensive multidisciplinary approach to optimise foetomaternal outcomes.
