Maternal cardiovascular morbidity and mortality associated with pregnancy in individuals with Turner syndrome: a committee opinion

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. This document replaces the 2012 document of the same name.
