Can sometimes achieve good long-axis view of aorta if lucky – otherwise may need to adjust above views using coronal views to guide, or utilise 3-point-planning
Sometimes useful for depicting anatomy:
Dilated & tortuous descending aorta with intra-mural haematoma (*)
Need to assess:general anatomy, dilation, shape
diameters (sinus, asc aorta, arch ± aortic annulus)
- use transverse views from this one
aortic valve function
Dilated aortic arch with small calibre entry and exit vessel. Note left subclavian arises from dilated section, and requires re-implantation at surgery
Type B aortic dissection in long-axis plane
Shows correct piloting of long-axis plane from transverse image – perpendicular to dissection flap
Metal artefact from clips suggesting tight re-coarctation. Catheter data showed no significant stenosis
High-coursing aortic arch (behind clavicle). Can be narrowed, or (as in this case) of normal calibre. May be due to persistence of 3rd branchial arch in fetal development, or failure of 4th branchial arch to migrate downwards
