{Reference Type}: Journal Article {Title}: Maternal cardiovascular morbidity and mortality associated with pregnancy in individuals with Turner syndrome: a committee opinion. {Author}: ; {Journal}: Fertil Steril {Volume}: 0 {Issue}: 0 {Year}: 2024 Jul 8 {Factor}: 7.49 {DOI}: 10.1016/j.fertnstert.2024.06.003 {Abstract}: In individuals with Turner syndrome, the risk of death from aortic dissection or rupture during pregnancy may be as high as 1%, and it is unclear whether this risk persists during the postpartum period owing to pregnancy-related aortic changes. Turner syndrome is a relative contraindication for pregnancy; however, it is an absolute contraindication for pregnancy in a patient with an aortic size index of >2.5 cm/m2 or an aortic size index of ≥2.0 cm/m2 with a documented cardiac anomaly or other risk factors.
