[Annulo-aortic ectasia].

Aortic regurgitation due to annular aortic ectasia was diagnosed in a 29-year-old woman with heart failure. The primary pathology of this disease is cystic medial necrosis of the ascending aorta with aneurysm formation and dilation of the aortic valve annulus. In successful surgical correction, the ascending aorta was replaced by a dacron prosthesis, the aortic valve by a prosthetic disc valve and the coronary arteries were reimplanted into the aortic graft.
