Management and Outcomes of Aortic Dissection in Pregnancy with Marfan Syndrome: A Systematic Review

In Marfan Syndrome (MFS), aortic dilatation is one of the main cardiovascular manifestations which deteriorate due to the physiological changes during pregnancy. We aimed to assess the up-to-date management and outcomes of aortic root dilation and dissection (AoD) in pregnancy with MFS.A systematic review was conducted and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Original studies published between January 1, 2001 and December 31, 2018 and which described the management and/or outcomes of AoD during or after pregnancy in women with MFS were included. Literature searches were conducted. The PubMed search was performed using terms "Marfan Syndrome" [Mesh] and "Pregnancy" [Mesh] whereas the Google Scholar search was for "Marfan" and "Pregnancy", all words anywhere in the article.The literature search yielded 177 articles on PubMed and 13,900 articles on Google Scholar. Assessment of full-text articles for eligibility after removal of duplicates from both databases yielded 12 eligible studies to be included in the final review.Women with MFS are at high risk of aortic dissection during pregnancy and women with aortic root 41-45 mm should consider avoiding pregnancy. Guideline-specific management of aortic aneurysms in pregnancy will reduce the risk of dissection. Diagnosis and Management of MFS need a multidisciplinary approach and team that should start working early in pregnancy. Further studies are needed to optimize medical and surgical approaches in addition to preconception counselling in highrisk subjects.
