Clinical presentation
Aortic root dilatation is often completely asymptomatic and found incidentally 2. In rare instances, it may present with a catastrophic complication such as an aortic dissection, aortic rupture, or congestive heart failure from aortic insufficiency.
Pathology
Aortic root dilatation can occur in isolation but is often associated with other conditions including:
