Ascending aortic aneurysm

Most ascending aortic aneurysms are caused by cystic degeneration of the aortic wall. Patients are mostly young and middle-aged, often accompanied by aortic valve sinus and annulus enlargement. In severe cases, the aortic valve leaflets cannot be closed when the heart is dilated, showing aortic valve insufficiency. However, the aortic valve leaflet itself was not significantly affected. Some patients may show signs of Marfan syndrome, such as a long head, high arches, slender trunks, limbs, and fingers, excessive extension of joints, malformations of the chicken breast or funnel chest, and congenital lens dislocation. Other causes of ascending aortic aneurysms are atherosclerosis, syphilitic aorticitis, and chest trauma.
