Abstract:
Aorto-left ventricular continuity destruction due to prosthetic valve endocarditis is rare, but it is one of the fatal complications after aortic root operation. We report a case of surgical treatment for prosthetic valve endocarditis after aortic root replacement. A 47-year-old man, who had undergone aortic root replacement with a composite graft was transferred to our hospital with sudden chest pain and high fever. Enhanced computed tomography showed a large space with contrast enhancement suggesting perivalvular leakage around the artificial composite graft. Emergency operation including aortic root re-replacement and reconstruction of the left ventricular outflow tract was performed successfully. We focused on its technical aspect.
