Aortic surgery during pregnancy: A retrospective case series in a single tertiary cardiovascular center

Objectives To evaluate maternal and fetal outcomes of aortic surgery during pregnancy. Methods We retrospectively analyzed eight pregnant patients undergoing aortic intervention between 2012 and 2025. Results The mean age was 30 years, and the mean gestational age was 19.5 weeks. Seven underwent open surgery in the second trimester, while one underwent thoracic endovascular aortic repair in the third trimester. Pathologies included aortic root aneurysm, often associated with Marfan syndrome. Procedures included valve-sparing root replacement ( n = 4), Bentall ( n = 3), and thoracic endovascular aortic repair ( n = 1). There was no maternal mortality. Six pregnancies resulted in live births, while two were complicated by intrauterine fetal demise. Conclusion Aortic surgery during pregnancy is associated with excellent maternal outcomes, though fetal risk remains significant.
