| bgcolor="LightGreen"|<nowiki>"</nowiki>'''1.'''  An echocardiogram is recommended at the time of diagnosis of Marfan syndrome to determine the aortic root and ascending aortic diameters and 6 months thereafter to determine the rate of enlargement of the aorta.

|-
| bgcolor="LightGreen"|<nowiki>"</nowiki>'''2.''' Annual imaging is recommended for patients with Marfan syndrome if stability of the aortic diameter is documented. If the maximal aortic diameter is 4.5 cm or greater, or if the aortic diameter shows significant growth from baseline, more frequent imaging should be considered.

|-
| bgcolor="LightGreen"|<nowiki>"</nowiki>'''3.''' Patients with Loeys-Dietz syndrome or a confirmed genetic mutation known to predispose to aortic aneurysms and aortic dissections (TGFBR1, TGFBR2, FBN1, ACTA2, or MYH11) should undergo complete aortic imaging at initial diagnosis and 6 months thereafter to establish if enlargement is occurring. ([[ACC AHA guidelines classification scheme#Level of Evidence|Level of Evidence: C]])<nowiki>"</nowiki>
|-
| bgcolor="LightGreen"|<nowiki>"</nowiki>'''4.''' Patients with Loeys-Dietz syndrome should have yearly magnetic resonance imaging from the cerebrovascular circulation to the pelvis. ([[ACC AHA guidelines classification scheme#Level of Evidence|Level of Evidence: B]])<nowiki>"</nowiki>
|-
| bgcolor="LightGreen"|<nowiki>"</nowiki>'''5.''' Patients with Turner syndrome should undergo imaging of the heart and aorta for evidence of bicuspid aortic valve, coarctation of the aorta, or dilatation of the ascending thoracic aorta. If initial imaging is normal and there are no risk factors for aortic dissection, repeat imaging should be performed every 5 to 10 years or if otherwise clinically indicated. If abnormalities exist, annual imaging or follow-up imaging should be done. ([[ACC AHA guidelines classification scheme#Level of Evidence|Level of Evidence: C]])<nowiki>"</nowiki>
