Abstract

Objectives: To systematically explore the relationship among the use of mechanical circulatory support (MCS), the timing of placement, and outcomes in pregnancy. Design: Using the National Inpatient Sample and National Readmissions Database, the authors performed a retrospective, cohort analysis of peripartum women who received MCS. Setting: United States hospitals. Participants: A weighted sample of women who received MCS during the antepartum, delivery, or postpartum period between 2002 and 2014. Interventions: MCS Measurements and Main Results: There were 1,386 women who received MCS during their admission. These women were older and had more comorbidities than women without MCS. The mean time from admission to device placement was 5.4 days for all women, and MCS use was highest in urban teaching hospitals. Overall, peripartum use of MCS has increased since 2002, but mortality did not change during the same period. After adjusting for potential confounders, the odds ratio for mortality when MCS was placed within 6 days of admission was 0.48 (95% confidence interval 0.23-0.98) with the adjusted probability of death rising from 18.6% to 32.5% when the device was placed on or after day 6. Conclusions: Similar to trends in the general population, use of MCS has increased in the peripartum period. Women receiving MCS were generally older and had more comorbidities than those not receiving MCS. Increased time to device placement may worsen mortality. Further research will help identify appropriate candidates and factors that improve survival.
