There are limited data regarding the outcome of pregnancy in women after intervention for coarctation of the aorta (CoA). The Texas Children's Hospital Cardiac Database was used to identify female patients with CoA born before 1980 who had undergone balloon angioplasty or surgery. Patients with Turner's syndrome and cyanotic congenital heart disease were excluded. A chart review and telephone interview were performed. Data collected included age at intervention, type of intervention, the need for reintervention, functional status, number of pregnancies, and pregnancy outcomes. Seventy-four patients met our criteria and we were able to contact 52. Eighteen patients (39%) were pregnant a total of 36 times. There were 3 spontaneous and 4 elective abortions. Preeclampsia complicated 4 pregnancies in 3 women (17% of primigravidas). One patient had systemic hypertension. Eleven infants were delivered by Cesarean section. There were 29 births, with an average weight of 3.0 kg. There were 5 preterm births, 4 to a teenage mother. Only 1 child (3%) had a congenital heart defect. Thus, in women with an arm-to-leg blood pressure gradient of <20 mm Hg after CoA repair, pregnancy is successful. The occurrence of congenital heart disease in the offspring was 3%. Preeclampsia was similar to that in the general population.
