Aortic root full detachment from the aortic annulus. aortitis role in the formation of a pseudoaneurysm to 3 years of an aortic valve replacement.

Results Redo open-heart surgery was performed, using femoral cannulation, mild hypothermia at 28°C, and circulatory arrest during 4 minutes, just to open and inspect the aorta. A big cavity acting as the aortic root, with irregular contour was observed. The floor of the cavity was the aortic prosthesis, the roof the beginning of true aortic root including both coronary ostia and the walls were formed by the roof of the left atrium, the main pulmonary artery, superior vena cava, right pulmonary artery and the rests of fibrotic and adhered pericardium. Aortic prosthesis seemed normofunctional, but the walls of the ascending aorta and aortic root were inflamed. A Bentall-De bono technique was performed. An Enterococcus faecalis was identified in the aortic wall by polymerase chain reaction. He was given six weeks of antibiotic therapy.
