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]
For many years, the gold standard treatment for patients with aortic valve disease and aortic root aneurysms was to replace both the aortic valve and the ascending aorta with a composite graft. 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.[10]
