[Pregnancy and delivery in women with coarctation of the aorta].
We report 2 cases of aortic coarctation in women aged 18.5 and 24 years, respectively. In 1 the malformation was found during gestation, while the other became pregnant after the diagnosis was made. Both had uneventful pregnancies and delivered healthy babies. Coarctation of the aorta is found in approximately 7% of those with congenital heart disease. The clinical diagnosis is made from the absence of femoral artery pulsations and low arterial pressure in arteries originating distal to the coarctation and hypertension in those proximal to it. Since it occurs mainly in males and is usually corrected during infancy, its incidence in pregnancy is low. Maternal morbidity may be high, since pregnancy increases the risk of aortic rupture or dissection, as well as of cerebral hemorrhage from rupture of an aneurysm of the circle of Willis. Surgical repair before conception reduces the risk of aortic complications during pregnancy, and also decreases the incidence of fetal complications, such as IUGR or congenital heart disease. The outcome of pregnancy is also influenced by coexistence of other malformations, such as bicuspid aortic valve which leads to infective endocarditis. In uncomplicated coarctation, pregnancy and delivery are usually uneventful. Cesarean section is done mainly for obstetric indications.
