Abstract

Simple aortic valve replacement was performed in a 59-year-old man whose ascending aorta was moderately dilated (45 mm) because he had no characteristics of Marfan's syndrome or other connective tissue diseases. However, about 20 months later, reoperation needed to be performed for aortic dissection of DeBakey type I. The pathological findings of the aortic wall obtained at the initial operation revealed cystic medial necrosis. The occurrence of aortic dissection after aortic valve replacement is uncommon but not rare, especially in patients with cystic medial necrosis and/or dilated aortic root. Therefore, in these patients, wrapping or replacement of the ascending aorta may be required at the same time of aortic valve replacement.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
