Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Annuloaortic ectasia?
Summarize this article for a 10 year old
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. Additional factors that contribute to this condition include osteogenesis imperfecta, inflammatory aortic diseases, intrinsic valve disease, Loeys-Dietz syndrome, Marfan syndrome, and operated congenital heart disease.[3]

On a gross level, there is a pear-shaped, symmetric enlargement due to proximal aortic dilation. The aortic wall dilatation at the commissural level causes the cusps to effectively shorten and prevent them from converging during systole, which results in aortic valve incompetence. The arch is typically spared from the aneurysmal process, though it may involve the entire ascending aorta. The ectatic aorta may experience dissections. Dissections of the ascending aorta are typically tiny, confined, and restricted. Aortic rupture can happen even if there is no dissection.[3]
The term was first coined by the American heart surgeon Denton Cooley in 1961.[4]
