Accurate Measurement of the Aorta

The Bicuspid Aortic Valve Foundation has a new blog. Embedded in their first post, there is an excellent video presentation focusing on diagnostic tools used to assess the condition of the BAV and the level of TAD (Thoracic Aortic Disease.) The most interesting thing I learned is that a dilated aorta is larger on systole than on diastole, and to obtain an accurate measurement CTs and MRIs should be "gated," which will reveal the aortic size on systole (maximum). This is the measurement that should be used when considering what size aneurysm triggers surgery. There is a lot more good info in the video. The blog is here:
