| ===Aortic Imaging Techniques===
| |
| {{cquote|
| |
| 1. Measurements of aortic diameter should be taken at reproducible anatomic landmarks, perpendicular to the axis of blood flow, and reported in a clear and
| |
| consistent format. (Level of Evidence: C)
| |
| | |
| 2. For measurements taken by computed tomographic imaging or magnetic resonance imaging, the external diameter should be measured perpendicular to the axis of blood flow. For aortic root measurements, the widest diameter, typically at the mid-sinus level, should be used. (Level of Evidence: C)
| |
| | |
| 3. For measurements taken by echocardiography, the internal diameter should be measured perpendicular to the axis of blood flow. For aortic root measurements, the widest diameter, typically at the mid sinus level, should be used. (Level of Evidence: C)
| |
| | |
| 4. Abnormalities of aortic morphology should be recognized and reported separately even when aortic diameters are within normal limits. (Level of Evidence: C)
| |
| | |
| 5. The finding of aortic dissection, aneurysm, traumatic injury and/or aortic rupture should be immediately communicated to the referring physician. (Level of Evidence: C)
| |
| | |
| 6. Techniques to minimize episodic and cumulative radiation exposure should be utilized whenever possible. (Level of Evidence: B)}}
| |
| | |
| ===Genetic Syndromes===
| |
| {{cquote|
| |
| | |
| 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. (Level of Evidence: C)
| |
| | |
| 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. (Level of Evidence: C)
| |
| | |
| 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. (Level of Evidence: C)
| |
| | |
| 4. Patients with Loeys-Dietz syndrome should have yearly magnetic resonance imaging from the cerebrovascular circulation to the pelvis. (Level of Evidence: B)
| |
| | |
| 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. (Level of Evidence: C)}}
| |
| | |
| ====Genetic Syndromes of Familial Thoracic Aortic Aneurysms and Dissections====
| |
| {{cquote|
| |
| | |
| 1. Aortic imaging is recommended for first-degree relatives of patients with thoracic aortic aneurysm and/or dissection to identify those with asymptomatic disease. (Level of Evidence: B)
| |
| | |
| 2. If the mutant gene (FBN1, TGFBR1, TGFBR2, COL3A1, ACTA2, MYH11) associated with aortic aneurysm and/or dissection is identified in a patient, first-degree relatives should undergo counseling and testing. Then, only the relatives with the genetic mutation should undergo aortic imaging. (Level of Evidence: C)}}
| |
| | |
| ===Bicuspid Aortic Valve and Associated Congenital Variants in Adults===
| |
| {{cquote|
| |
| | |
| 1. First-degree relatives of patients with a bicuspid aortic valve, premature onset of thoracic aortic disease with minimal risk factors, and/or a familial form of thoracic aortic aneurysm and dissection should be evaluated for the presence of a bicuspid aortic valve and asymptomatic thoracic aortic disease. (Level of Evidence: C)
| |
| | |
| 2. All patients with a bicuspid aortic valve should have both the aortic root and ascending thoracic aorta evaluated for evidence of aortic dilatation. (Level of Evidence: B)}}
| |
| | |
| ===Inflammatory Diseases Associated with Thoracic Aortic Disease===
| |
| {{cquote|
| |
| | |
| 1. Initial therapy for active Takayasu arteritis and active giant cell arteritis should be corticosteroids at a high dose (prednisone 40 to 60 mg daily at initia-
| |
| tion or its equivalent) to reduce the active inflammatory state. (Level of Evidence: B)
| |
| | |
| 2. The success of treatment of patients with Takayasu arteritis and giant cell arteritis should be periodically evaluated to determine disease activity by repeated physical examination and either an erythrocyte sedimentation rate or C-reactive protein level. (Level of Evidence: B)
| |
| | |
| 3. Elective revascularization of patients with Takayasu arteritis and giant cell arteritis should be delayed until the acute inflammatory state is treated and quiescent. (Level of Evidence: B)
| |
| | |
| 4. The initial evaluation of Takayasu arteritis or giant cell arteritis should include thoracic aorta and branch vessel computed tomographic imaging or magnetic resonance imaging to investigate the possibility of aneurysm or occlusive disease in these vessels. (Level of Evidence: C)}}

| CMR of thoracic aortic disease CMR may be used for defining the location and extent of aortic aneurysms, erosions, ulcers, dissections; evaluating postsurgical processes involving the aorta and surrounding structures, and aortic size blood flow and cardiac cycle–dependent changes in area.
