[Dissecting aneurysm of the ascending aorta as a late complication of the treatment of acquired defects of the aortic and mitral valves].

A diffuse aneurysm of the ascending aorta was observed five months after prosthetic valve implantation in to mitral and aortic orifices because of the acquired valvular heart disease. The main factor predisposing to the formation of a false aneurysm was an infection of the endocardium and ascending aortal wall which were observed previously during cardiac surgery. The diagnosis, based on the clinical symptoms and non-invasive investigations, was later confirmed with aortography and intra-operatively.
