Analysis of Aortic Area/Height Ratio in Patients With Thoracic Aortic Aneurysm and Type A Dissection

Aortic dissection frequently occurs in patients with normal aortic diameter. The authors indexed aortic area to height and correlated with absolute aortic diameter. Using this new index, they were able to identify a significant proportion of patients with thoracic aortic aneurysms who were at increased risk of aortic complications.
