Key result
Heart disease complicates ~0.4% of deliveries, led primarily by mitral valve diseases.
Why the study?
Pregnant women diagnosed with cardiac disease require better understanding of pregnancy complications and management strategies due to physiological changes and increasing maternal age.
Observational (n=37,520)
No
Heart disease complicates 0.35% of pregnancies, most commonly due to mitral valve disease, highlighting the need for pre-pregnancy cardiovascular assessment.

Retrospective data on cardiac disease in pregnancy may aid risk assessment; leaves open need for prospective validation before guiding practice.
Purpose: Pregnant women who were diagnosed with a cardiac disease, from an echocardiogram before or during pregnancy, were retrospectively analysed in this study. Materials and Methods: Pregnant women who delivered at our training and research hospital in the time period of 2009-2014 were included in this study. The records of women who gave birth were screened retrospectively. Results: Patients who were diagnosed with an echocardiogram before or during pregnancy were considered as pregnant women with heart diseases. Patients who underwent pregnancy termination due to decompressed heart diseases were excluded from the study. 37 520 deliveries were examined. The number of complicated pregnancies with heart disease was 132 (0.35%), 45 of these patients had a caesarian section (C/S). Mitral valve diseases were found to be the most common cause of heart disease. Heart disease complicating pregnancy is increasing with advanced maternal age. Conclusion: Understanding the physiological changes in pregnancy and their effect on specific cardiac conditions forms the basis of management during pregnancy. Close surveillance should be offered for these women. Prior to pregnancy, patients should receive a cardiovascular assessment and counseling, this should be a primary goal.

Elçi et al. (2020) conducted an observational in Pregnancy complicated by heart disease (n=37,520). Heart disease during pregnancy vs. Pregnancies without heart disease was evaluated on Prevalence and characteristics of heart disease in pregnancy. Among 37,520 deliveries, 132 were complicated by heart disease, with mitral valve diseases being the most common cause and 34% of these patients requiring a cesarean section.
