Contraceptive Choices in the Immediate Postpartum Period in Women With Cardiac Disease

Abstract

Maternal cardiac disease (MCD) is associated with increased maternal and neonatal morbidity and mortality. Because unplanned pregnancies are especially risky, active use of reliable contraception is critical in this population. Studies in the noncardiac population have demonstrated that the postpartum period is an ideal time to address contraceptive plans. This retrospective cohort study was designed to describe contraceptive choices in women with MCD in the immediate postpartum period and to identify factors associated with specific contraceptive plans. We included women with MCD who delivered from January 2008 to September 2017 at a tertiary care institution with a multidisciplinary obstetrics and cardiology team. Maternal demographics, specifics of MCD, obstetrical outcomes, and contraceptive plans were obtained through chart review. Contraceptive plans were categorized into highly reliable methods (sterilization or long-acting reversible contraceptive methods) or less reliable methods (nonlong-acting reversible contraceptive methods or no contraception). In the 254 women included in this study, 40% planned to use highly reliable methods, while 60% planned to use less reliable methods. Women with cardiomyopathy were more likely to choose a highly reliable method of contraception (adjusted odds ratio 2.6, 95% confidence interval 1.2 to 5.7), a reassuring finding, given the particularly high risk of poor pregnancy outcome with this diagnosis. There were no differences in other cardiac diagnoses between the 2 contraceptive groups. In conclusion, the finding that <50% of postpartum women with MCD plan to use a highly reliable method of contraception warrants further examination to identify and address barriers to reliable contraceptive plans in this high-risk population.
