Increased Risk of Aortic Dissection Associated With Pregnancy in Women With Turner Syndrome: A Systematic Review.
(Journal Article;Systematic Review)
IMPORTANCE: Turner syndrome (TS) is one of the most common chromosomal abnormalities in women. The condition is characterized by gonadal dysgenesis and is associated with structural cardiac abnormalities. Assisted reproductive technology with oocyte donation may be successful but places women with TS at increased risk of aortic dissection and death. OBJECTIVE: To summarize all cases of aortic dissection associated with pregnancy in women with TS and provide guidance regarding the safety of pregnancy. EVIDENCE ACQUISITION: Systematic review of PubMed for reports of women with TS, aortic dissection, and pregnancy. RESULTS: There are 14 total reported cases of aortic dissection associated with pregnancy in women with TS. Ten of these cases occurred during pregnancy or in the first month postpartum. The majority of affected pregnancies resulted from oocyte donation, 2 of which were multiple gestations. Two women had a documented history of hypertension, and 3 pregnancies were complicated by preeclampsia. Bicuspid aortic valve and coarctation of the aorta were the most common associated cardiac anomalies. More than half of women had some degree of aortic dilatation. Two women had no identifiable risk factors. CONCLUSIONS AND RELEVANCE: Women with TS who desire pregnancy must be thoroughly counseled regarding the increased risk of aortic dissection during pregnancy and postpartum. Preconception consultation with maternal-fetal medicine, reproductive endocrinology, and cardiology is necessary along with a comprehensive physical evaluation. If women with TS choose to pursue pregnancy, they require rigorous cardiac monitoring each trimester during pregnancy and postpartum.
