Abstract
Aortic dissection (AoD) in pregnancy, particularly in women with Marfan syndrome (MFS), carries a high risk for both maternal and fetal mortality. Multidisciplinary management is essential for successful outcomes in these complex cases. We present a 26-year-old G1P0 female patient at 33 weeks gestation with chronic hypertension and MFS who developed mild symptoms of type A AoD. She underwent successful concomitant cesarean section and emergency aortic repair. Through multidisciplinary coordination of obstetrics with cardiothoracic surgery (CTS) and neonatal teams, both mother and infant recovered without major complications. This case highlights the critical need for early recognition, imaging, and multidisciplinary collaboration in pregnant patients with known risk factors of life-threatening conditions, such as AoD. Stricter screening protocols and frequent monitoring may prevent catastrophic outcomes in these high-risk patients.
