Predictors of aortic dilation in patients with coarctation of the aorta: evaluation with dual-source computed tomography.

Ascending and post-coarctation aortic diameters or dilations were both associated with the degree of coarctation. By comprehensively evaluating the aortic diameters and associated malformations including collateral circulation, DSCT can aid in stratification of risk for aortic dilation in patients with CoA.
