Abstract

Objective: We assessed the impact of pregnancy on long-term cardiac outcomes in women with prior surgery for congenital pulmonary valve anomalies. Study Design: Data on all reproductive age women with prior pulmonary valve repair or replacement, cared for at a tertiary institution over a 10-year period, were analyzed. Kaplan-Meier curves and proportional hazards models were estimated to assess the impact of pregnancy and multiparity on a composite long-term adverse outcome defined as death, heart failure, or unanticipated cardiac surgery. Peripartum cardiac complications were also assessed. Results: Thirty-three parous and 20 nulliparous, nonpregnant controls with primary pulmonary valve replacement or repair were identified. Among the parous women, there were 95 pregnancies (median, 3.0; 1-10) resulting in 81 live births. Peripartum cardiac complications occurred in 28 (29.8%; 95% confidence interval, 20.4-39.2) of the pregnancies. A composite adverse long-term cardiac outcome occurred in 17 of 33 parous women, over 417 person-years (4 per 100 person-years) and 1 of 20 nulliparous women over 258 person-years (0.4 per 100 person-years); women with pregnancies were more likely at any point in time to have a composite long-term adverse cardiac outcome compared with nulliparous controls. Women with 2 or more pregnancies were more likely to have a composite adverse cardiac outcome than those with less than 2 pregnancies (hazard ratio, 8.8; 95% confidence interval, 1.5-50.3). Conclusion: Peripartum cardiac complications are common in women with prior pulmonary valve repair or replacement. Pregnancy appears to increase the risk of long-term adverse cardiac outcomes in these patients when compared with nulliparous controls.
