Clinical Significance of Aortic Root Modification Associated With Bicuspid Aortic Valve in Marfan Syndrome An Observational Cohort Study

摘要

BACKGROUND: Both bicuspid aortic valve (BAV) and Marfan syndrome have been associated with aortic dissection risk, but it is unknown whether the presence of BAV is associated with an increased aortic risk in patients with an FBN1 gene mutation. We evaluated aortic diameters, aortic valve function, and aortic shape in Marfan syndrome patients with and without BAV and reported aortic events during follow-up.
