New Predictor of Aortic Enlargement in Uncomplicated Type B Aortic Dissection Based on Elliptic Fourier Analysis

Sato and colleagues applied elliptic Fourier analysis to morphological aortic measurements from 80 patients with uncomplicated type B aortic dissection. The patients were divided in two groups according to aortic enlargement during follow-up. The shape of the aortic diameter at initial operation was a significant predictor of further morphologic development.
