Annuloaortic ectasia is characterized by pure aortic valve regurgitation and aneurysmal dilatation of the ascending aorta.

[2] Men are more likely than women to develop idiopathic annuloaortic ectasia, which usually manifests in the fourth or sixth decades of life.

[3] On a gross level, there is a pear-shaped, symmetric enlargement due to proximal aortic dilation.

[5] Symptoms include dyspnea, respiratory distress, heart failure, atrial tachycardia,[6] pain, cardiac tamponade,[7] palpitations, and malaise.

This also applies to patients with different levels of AI and annuloaortic ectasia, where the aortic valve may be largely preserved without any structural abnormalities.
