[Acute type A aortic dissection in pregnant patient with Marfan syndrome. Report of one case]. / Disección aórtica y síndrome de Marfán en el embarazo. A propósito de un caso clínico.

Aortic dissection is a life-threatening disease that requires immediate surgical intervention. Marfan syndrome is a hereditary disease with an autosomal dominant transmission, which affects the connective tissue, with skeletal, cardiovascular and ocular involvement. It is one of the most prevalent connective tissue disorders, presenting a risk of aortic dissection of approximately 1% even without dilatation of the aorta. When dissection occurs during pregnancy and requires surgical intervention (type A dissection), maternal mortality is high (2096-30%). We report a 38 year-old woman with Marfan syndrome that had an acute type A aortic dissection and severe aortic regurgitation at 37 weeks of gestation. The patient underwent a cesarean section and delivered a healthy baby. Afterwards, aortic valve repair and ascending aortic replacement was successfully performed under circulatory arrest with deep hypothermia. Additionally mitral valve repair for degenerative disease with posterior, autologous pericardium mitral valve ring was performed.
