Abstract

We replaced the aortic root in a 43-year-old woman with Takayasu's aortitis associated with prosthetic aortic valve detachment. The patient's aortic valve had been replaced when she was 31 years old with a mechanical prosthesis to treat aortic regurgitation. Though C-reactive protein was kept almost normal with prednisolone, complete atrioventricular block suddenly appeared 12 years after the first operation. After the implantation of an artificial pacemaker, we closely followed up aortic root status. Aortography and echocardiography showed that the valve moved up and down, probably due to enlargement of the sinuses of Valsalva, without perivalvular leakage. We removed the prosthetic aortic valve, which was partially detached from the aortic valve ring at the right- and non-coronary cusps and successfully replaced the aortic root with a mechanical prosthesis inserted into a 26 mm woven graft. Although the postoperative course was uneventful, we closely continue to observe the case and to administer of antiinflammatory medication.

Aortic Coarctation

Aortic coarctation is a congenital condition characterized by narrowing of the aorta. Discover the latest research on this disease here.

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.
