Samenvatting

Objective: Women with repaired coarctation of the aorta (rCoA) are at risk of hypertensive disorders and other complications during pregnancy. Hypertensive disorders in pregnant women are associated with inadequate uteroplacental flow, which is related to adverse offspring outcome. The aim of this study was to investigate the relationship of maternal cardiac function, placental function and pregnancy complications in women with rCoA.

Methods: We included 49 pregnant women with rCoA and 69 controls from the prospective ZAHARA-studies (Zwangerschap bij Aangeboren HARtAfwijkingen, pregnancy in congenital heart disease). Clinical evaluation, echocardiography and uteroplacental Doppler flow (UDF) measurements were performed at 20 and 32 weeks gestation. Univariable regression analysis was performed.

Results: Comparison of rCoA and healthy women. In women with rCoA, tricuspid annular plane systolic excursion (TAPSE) decreased during pregnancy (25.7 mm to 22.8 mm, P = 0.006). UDF indices and pregnancy complication rates were similar in both groups. Offspring of rCoA women had lower birth weight (3233 g versus 3578 g, P = 0.001), which was associated with beta-blocker use during pregnancy (beta = -418.0, P = 0.01).

Association of cardiac function and UDF. Right ventricular (RV) function before pregnancy (TAPSE) and at 20 weeks gestation (TAPSE and RV fractional area change) were associated with impaired UDF indices (umbilical artery pulsatility index at 20 weeks beta = -0.02, P = 0.01, resistance index at 20 and 32 weeks beta = -0.01, P = 0.02 and beta = -0.02, P = 0.01 and uterine artery pulsatility and resistance index at 20 weeks gestation beta = -0.02, P = 0.05 and beta = -0.01, P = 0.02).

Conclusions: Women with rCoA tolerate pregnancy well. However, RV function is altered and is associated with impaired placentation.
