Root Dilatation Is More Malignant Than Ascending Aortic Dilation

The Yale database of 1162 patients with ascending aortic aneurysms was queried.  Analysis suggested root dilatation was more significant in predicting adverse events than mid -ascending aortic dilatation, with short stature as a serious risk factor.  Hinge points at 5.0 and 5.25 cm respectively were identified.  The authors suggest these paramenters should be considered as intervention criteria.
