Overview
The diagnosis of a thoracic aortic aneurysm is often made as an incidental finding on transthoracic echocardiography (dilated aortic root) or on trans esophageal echocardiography (enlarged ascending aorta or aortic arch). The definitive diagnosis is made using CT angiography but MRA is also an excellent test. Once diagonosed, serial CTA (or MRA) are recommended every 6-12 months.
2010 ACC/ AHA Guidelines for the Diagnosis and Management of Patients with Thoracic Aortic Disease (DO NOT EDIT)[1]
Aortic Imaging Techniques to Determine the Presence and Progression of Thoracic Aortic Disease (DO NOT EDIT)[1]
| Class I |
| "1. 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)" |
Aortic Imaging in Genetic Syndromes (DO NOT EDIT)[1]
| Class I |
| "1. An echocardiogram is recommended at the time of diagnosis of Marfan syndrome to determine the aortic root and ascending aortic diameters (see(Figure 5))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)" |
